maziggy 0d21239e18 Send AMS tray colours as uppercase hex (issue #2987)
Assigning a spool to an AMS slot unassigned it again seconds later, and
the slot's colour changed at the same time. It presented as Bambu Studio
and Bambuddy fighting over the slot. The reporter's log shows Bambuddy
losing to itself.

P1S firmware 01.10.00.00 reads every lowercase hex letter in an AMS
tray_color as a zero, and hides it completely: the command response
echoes back the value that was sent and reports result "success", so
only the next AMS push says what was really stored. The spool-assign
path sent spool.rgba verbatim and that column stores lowercase. From the
bundle:

  sent 09ff00ff  ->  AMS reports 09000000
  sent ff5100ff  ->  AMS reports 00510000
  sent 090000FF  ->  AMS reports 090000FF

That is the visible colour change, and it is also what deleted the
assignment. The auto-unlink sweep asks whether the slot still matches
the spool assigned to it; the mangled colour no longer did, so the
assignment Bambuddy had made four seconds earlier was removed.
colors_similar('09000000', '09FF00FF') is False, which is the whole of
it.

Re-assigning could not recover, because the Configure Slot dialog seeds
its colour from whatever the printer currently reports. It wrote the
mangled colour back and cemented it, which is the loop the report
describes in its steps 4 and 5.

Colours are now uppercased where the command is assembled rather than in
each of the four routes that configure a slot. A caller that forgets is
exactly how this arrived. Nothing else changes: no padding, no invented
alpha, no six-to-eight widening, and tray_type and tray_sub_brands keep
their case, where it carries meaning -- "PLA Matte" is a product line,
"PLA MATTE" is not.

Two paths deliberately left alone. The developer-mode probe re-sends the
colour the printer itself just reported so that the probe is inert;
uppercasing there would turn it into a write. And the Virtual Printer
forwards the slicer's own command verbatim -- Studio could in principle
hit the same firmware bug, but nothing here evidences that it sends
lowercase, and rewriting a slicer payload inside a transparent proxy is
not a change to make on a hunch.

Two more defects from the same log.

A spool with a brand and no subtype was configured with the string
"None" in its name: the branded branch interpolated spool.subtype
without checking it while the unbranded branch guarded it, so
"Sunlu PLA Matte None" went on the wire and into Studio's display.

And the FTP log is readable again. A 426 whose bytes Bambuddy has
already verified against the printer is how Bambu FTPS normally ends a
transfer, not a fault, so it drops from WARNING to INFO. It fired 54
times in this one bundle, every one followed by a completed upload, and
it was burying the 26 TLS handshake failures in the same log that
actually cost the reporter two prints. A 426 whose bytes do not verify
is still an error and still fails the upload.

The handshake failures themselves are printer-side FTPS cool-off under
load and are not touched here.

maziggy cc39acfc74 Ask a printer that refuses FTPS what it actually said (issue #2780)
@grolmus measured a 9-printer farm and the numbers settle what this
failure is not. Reproduced here, three results:

  cleartext "421" banner on the TLS port
    -> [SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1032)
  1.2-only server, client forced to 1.3
    -> [SSL: TLSV1_ALERT_PROTOCOL_VERSION]
  1.2-only server, an uncapped client
    -> negotiates 1.2 and connects

The first is byte-for-byte what the farm logs. So WRONG_VERSION_NUMBER
means the printer's first bytes were not a TLS record, a version
mismatch cannot produce it, and reaching a 1.2-only peer needs no cap.

What it still does not say is WHICH cleartext message, and that is the
part that would name the fault. OpenSSL has eaten those bytes by the
time the exception surfaces, so on this error the client now opens one
plain connection and reads them. The log then carries the printer's own
words -- an FTP refusal such as "421 Too many connections" would settle
it outright -- marked as the line to quote in a report. This gets the
answer from every affected install rather than from the one farm able
to take a packet capture.

Three things keep it from making the suspected fault worse:

- The failed socket is closed BEFORE the probe opens its connection.
  Holding a dead handshake open across a second connect to a printer
  that may be out of connection slots is the leak #2780's own cleanup
  was added to stop.
- It asks once per cool-off window, not once per attempt. Checked
  before the new deadline is written, so a live entry means an earlier
  failure already asked -- which matters because a dispatch ignores the
  cool-off (#2898) and reaches this branch four times.
- Connect and read share one timeout budget rather than getting one
  each.

Only WRONG_VERSION_NUMBER is probed. A protocol-version alert means the
peer did speak TLS, so there is nothing in the clear to read and the
probe would only sit out its timeout. A vsFTPd answering its connection
limit by accepting and staying silent -- the other half of the standing
theory -- arrives as a handshake timeout and lands on that branch
instead; there is a test saying so, because widening the trigger later
would look like an improvement.

The profile registry is corrected to what was measured. Its docstring
claimed "the P2S evidently does offer 1.3"; six P2S units refuse it.
Worse, the X2D (#1638) and H2C (#2582) entries were capped on the
reading that WRONG_VERSION_NUMBER came from a TLS-1.3 ClientHello,
which cannot happen -- so the cap is not what changed those outcomes
and both are now marked RE-TEST WANTED. They are kept rather than
removed: their reporters saw the symptom clear, nobody here has that
hardware, and the entry costs nothing on a printer that does not offer
1.3 anyway. The P2S entry (#1401) is a different symptom -- a 426
truncation mid-transfer -- and is the only one a session-ticket problem
could explain, though grolmus's firmware refuses 1.3 there too.

Both measurements are pinned by tests, so the explanation stays
falsifiable instead of becoming the next set of confident wrong
comments. Two existing cool-off tests now count two connections where
they counted one; the promise they exist for -- contacted twice, not
~110 -- is unchanged, and they say why rather than carrying a new
number.

maziggy d227d42272 Let a print with no 3MF be given its filament weight (issue #1820)
When the sliced file stays somewhere Bambuddy cannot read, the archive is
built from the printer's report alone and carries no weight. Nothing could
supply one afterwards: rescan reads the figure out of the 3MF, and that
archive has no file to read. The reporter's H2S print left 46.16 g on the
spool with nothing recording it, and he corrected Spoolman by hand.

Edit Archive now has a Filament used (g) field. It is written to the
archive's most recent run as well, because the Projects roll-up and the
Prometheus counter sum PrintLogEntry rather than the cards - correcting
only the archive would fix the display and leave every aggregate reading
the old figure, or none at all.

But not over a figure the run measured for itself. A run's grams come from
the tracked spool delta when there is one and only fall back to copying
the archive's estimate when there is not, so mirroring unconditionally
would overwrite a measurement with a typed estimate. The mirror now takes
a run that has no figure, or one holding exactly what this archive held -
which also makes the undo complete, since clearing the archive clears the
copy it made and leaves a measured run alone.

The field is text rather than a number input. A number input reports an
empty string for anything the browser judges malformed, a decimal comma in
a locale that does not expect one included, and that reads here as "the
user cleared it" - it would have wiped a good figure while the field still
showed what was typed. Filtering on the way in keeps what is displayed and
what would be sent the same string, and clamps it to the range the API
accepts: this modal has no error surface, so a refused save looks like
nothing happened at all.

Saving also invalidates the archive's runs query. The Print Log this modal
renders at its top reads them separately and kept serving the pre-edit row,
so a correction looked like it had not taken - true for the status and
failure-reason mirrors since #1444 as well.

Second half of the same report: the internal-storage probe (#2856) logged
which file it found but not where. On a printer that keeps uploads for
weeks - the reporter has months of them in /cache - a reprint of a name
that was re-sliced but never re-sent can match an older copy, and without
the directory that mismatch is invisible rather than merely rare. The
download helper returns the path that served the file instead of a bare
flag; every caller only ever tested it for truth.

maziggy fffa68ec55 Explain a print that never reached the printer's card, instead of sweeping for it (#2780)
Bambuddy reads a print's 3MF, cover and timelapse over FTPS on port 990,
which on every Bambu model serves external storage only. Under some
configurations H2-series and P2S firmware keeps the sliced file on
internal storage, where Bambu Studio put it over the port-6000 service,
and then no path on 990 can find it.

The print command has always said which of the two it used -- `url` reads
ftp://<name> or brtc://emmc/<name>. We discarded it and swept anyway:
~110 connections per print, all certain to fail, ending in an archive
card with nothing on it and no stated reason. In the reporter's bundle
all 35 dispatches to their H2C and P2S said internal storage, all 25 to
their X1C said external, and all 44 empty cards belonged to the first two.

Read the field, skip the sweep when it cannot succeed, and record which
reason applied. A printer that uses the card is unaffected, and so is one
we have no answer for -- silence is not evidence, and reading it as bad
news would break archives that work today.

The answer is held per print and dropped when that print ends, rather
than kept as a standing fact about the printer. Plenty of prints never
announce themselves: 14 of the 79 print starts in that bundle arrived
with nothing on the request topic, started from the printer's own screen
or picked up after a restart. Left standing, one slicer print to internal
storage would suppress the lookup for every screen-started print after
it, on a printer whose files really are on the card. The sticky reading
is kept for the connection diagnostic alone, which is run after the print
that prompted it and would otherwise have nothing to report.

Two things that pointed the wrong way go with it. The archives banner
told everyone to enable "Store sent files on external storage"; the
reporter had it on for the whole three weeks and it would not have
helped. The diagnostic passed a printer whose slot was empty, because it
read only the toggle -- an empty slot is now a failure naming the slot,
and a printer that has storage and still used its own is a warning. On
P1-series that empty-slot failure yields to the existing unsupported-model
skip: the toggle cannot be switched on there at all, so telling the
operator to insert a card would promise a fix inserting a card does not
deliver (#2524).

Also close FTP sockets on the failure paths, which dropped them for the
garbage collector -- 1813 in a day in that bundle -- and drop the advice
to restart the printer, which the reporter tried twice while a single
manual connection to the same printer handshook cleanly.

This does not make the affected prints archive in full; that needs the
port-6000 protocol tracked in #2762.

maziggy 91acac2b35 Stop retrying a printer whose FTPS handshake fails, and name the cause (#2780)
Two printers went on printing while every archive they produced held nothing
but a filename. Bambuddy opened port 990, the printer accepted the connection
and answered with something that was not TLS, and connect() logged a warning
and returned False -- indistinguishable, to every caller, from "the file is
not at this path". So the 3MF lookup walked all six filename variants across
five directories with four retries each, the cover endpoint ran its own
sixteen-path sweep, and the timelapse scan added four more, all against a
sixteen-path sweep, and the timelapse scan added four more, all against a
printer that could not have answered any of them. One reporter's log carried
1813 identical handshake failures, another's 3511.

The evidence says this is the printer's own file service getting stuck, not a
model, firmware or TLS-configuration problem. In #2780's bundle the same two
printers ran clean from 22 July to 4 August and failed again from the 5th; a
second bundle shows an X2D serving files for five days, flipping on 19 July,
then failing every connection for eight days with zero successes. The same
models and firmware appear in roughly twenty other bundles with no occurrences
at all. Both bundles show it happening with cap_tls_v1_2 in effect -- the X2D
and H2C entries in ftp_profiles were added on analogy with P2S to fix exactly
this symptom, and the reporter's own debug line proves they do not.

An ssl.SSLError from connect() now opens a five-minute cool-off for that
printer. Subsequent connects return False without touching the network, so a
wedged printer is contacted twice an hour instead of hundreds of times a
minute, and the single warning that is logged names the remedy. The cool-off
is dropped on expiry rather than kept, so the map holds one key per currently
wedged printer. ftps_handshake_blocked() lets the sweeps stop: the 3MF lookup
abandons the remaining paths and skips the directory-walk fallback, the cover
endpoint returns 503 naming the file service instead of a 404 that reads as
"this print has no thumbnail", and the timelapse scan separates 503 (cannot
reach the printer) from 404 (no timelapse directory) -- one 500 used to cover
both, which is what the reporter hit when reproducing.

The Connection Diagnostic completed a bare TCP connect to 990, which is why it
reported the port green throughout: the port is open, it is what is behind it
that is broken. It now completes a real implicit-TLS handshake using the
model's own ftp_profiles cap, so a pass means the FTP client would also get
through. An open port that cannot negotiate reports warn with reason no_tls,
selecting a new message in all 13 locales that points at a printer restart
rather than at the firewall. No login is attempted, so this stays valid in the
pre-save Add Printer flow.

The cool-off tests run against a real socket that accepts on 990 and replies
with a plaintext FTP banner, reproducing WRONG_VERSION_NUMBER rather than
mocking ssl. The autouse fixture clearing _mode_cache now clears the cool-off
map too -- every test here talks to 127.0.0.1, so one left behind would make
the next test's connect() a no-op.

maziggy 3fd3ec06b9 fix(ftp): stop a slow upload from being retried on top of itself (#2529)
upload_file_async carried a flat 600s wall-clock deadline and ran the
transfer via asyncio.wait_for(run_in_executor(...)). wait_for cancels the
future, not the executor thread. A 96 MB 3MF to an A1 over WiFi sustains
~75 KB/s and needs ~20 minutes, so the await gave up at ~70 MB, returned
False, and with_ftp_retry started a second STOR of the same file onto the
same printer while the first was still streaming. The reporter filmed two
transfers of one job climbing in parallel at 2% and 72%; the print never
landed and the printer read as having a flaky network.

The deadline is now derived from the file size against a 25 KB/s floor, so a
slow-but-healthy transfer can finish — a link that has actually died is
caught within socket_timeout by the blocking sendall, which is what should be
detecting failure. A deadline expiry now stops the transfer for real: the
worker is signalled, raises UploadCancelled from its progress callback, and
upload_file's existing cancel path breaks the send loop and deletes the
partial file. with_ftp_retry never retries that, and a per-printer lock makes
overlapping uploads impossible however they were triggered.

maziggy 7190fc2d13 fix(logs): demote benign "not connected" + "may linger" warnings
Two warnings polluting every A1 support bundle on healthy prints, both
  unrelated to the timelapse-default behaviour the issue actually reports.

  1. mqtt_bridge.py's post-bind nudge calls request_status_update on the
     real printer's MQTT client to populate the bridge cache without
     waiting for the next periodic pushall. The bind frequently races the
     TLS handshake, especially on A1 firmware. Skip the nudge when
     state.connected is False — the periodic pushall fills the cache
     anyway. The WARNING in bambu_mqtt.py stays for the genuinely-
     actionable callers (refresh-status API, bug reporter).

  2. Post-finish SD-card cleanup (and the symmetric forced-timelapse dir
     walk) used delete_file_async's bool return to drive a WARNING when
     all candidates failed. A1 firmware self-cleans the SD card before
     our cleanup runs — every candidate FTP-DELE returns 550, we burn
     the retry budget, then WARN on a successful print. Introduce
     DeleteResult.{DELETED,NOT_FOUND,FAILED} so the helpers only WARN
     on real network/auth/transient failures. NOT_FOUND advances to the
     next candidate without consuming the 2s backoff. User-facing delete
     endpoint returns 404 on NOT_FOUND.

maziggy d6d3fa2f99 chore(security): nosec false-positive Bandit findings in tests
PR #1434 CI flagged 5 B402 (ftplib import) in test_bambu_ftp.py and 2
  B108 (hardcoded /tmp) in test_print_start_assigns_printer_id_to_vp_archive.py.
  Both are intentional in tests: the FTP client tests need real ftplib
  exception classes to construct mock 426 responses, and the /tmp path is
  a MagicMock attribute never written to. Marked with `# nosec B402` /
  `# nosec B108` plus a one-line justification each, matching the

maziggy 9c934c905d fix(ftp): tolerate transient 426 when file is intact on the printer (#1417 follow-up)
Previous daily build (1fac0276) tightened the post-STOR voidresp
  handler to fail on any ftplib.Error, stopping Bambuddy from
  sending a print command for a truncated 3MF. Reporter
  (@enjoylifenow on a P2S) then confirmed — after a clean SD-card
  filesystem check, reformat, and power cycle — that v0.2.4.1
  worked on the same hardware. That proves the 426 returned by
  this firmware revision is noise: the TLS data-channel close
  races the 226 confirmation, server reports failure, file is in
  fact on the SD card.

  Reverting wholesale would re-introduce the silent-truncation
  bug from the original fix. Narrow the rule instead: after an
  ftplib.Error from voidresp, run an FTP SIZE against the upload
  path. SIZE matches the local file size → warn and proceed
  (the reporter's case). SIZE mismatch, or SIZE itself raises →
  fail loudly with full diagnostics (the original tightened
  behavior — preserved).

  Applied identically to upload_file() and upload_bytes() so the
  A1-compatibility manual-transfer path is covered.

  Tests: two regressions from the previous round renamed and
  split into intact / truncated / size-check-fails. Intact-file
  tests inject SIZE explicitly because pyftpdlib only flushes on
  a clean voidresp — which can't happen when we monkeypatch
  voidresp to raise. Docstring spells that out. 87 FTP unit tests
  green; 118 FTP-touching tests across unit+integration green;
  ruff clean.

  The View-Timelapse-greyed-out behavior #1417 was originally
  about stays untouched; once the reporter confirms upload
  reliability is back, that diagnosis continues on a healthy
  install.
2026-05-19 11:32:22 +02:00
maziggy 1fac027654 fix(ftp): raise on ftplib.Error from voidresp instead of proceeding
bambu_ftp.upload_file (and upload_bytes) wrapped the voidresp() call in a
  broad "except Exception: log warning and proceed" because H2D printers
  can take 30+ seconds to send the 226 and we don't want to fail on that.
  But the same handler was swallowing ftplib.error_temp (e.g. 426 "Failure
  reading network stream") from buggy printer firmware, which explicitly
  means the data stream was cut mid-transfer and the file on the SD card
  is partial.

  Bambuddy then sent the print command anyway, and the printer surfaced a
  generic "unable to parse 3mf file" error 30 seconds into the print
  attempt -- with nothing in the log on the user side to suggest the
  upload had actually failed.

  Split the catch: ftplib.Error subclasses (server-reported failure)
  re-raise so the outer handler returns False; everything else (socket
  timeout etc.) keeps the existing proceed-with-warning behaviour so the
  H2D 226 tolerance survives.

  Two regression tests patch _ftp.voidresp to raise error_temp("426 ...")
  and assert both upload_file() and upload_bytes() return False.

  The underlying P2S firmware / TLS-data-channel issue that triggers the
  426 for the reporter is separate -- this change just stops Bambuddy from
  hiding it.

maziggy 3bb99759d2 fix(archive): never delete persistent files in 3MF cache cleanup (#1212)
Daily builds since 889c8bd8 (Apr 29) silently destroyed archive copies
  and library file bytes on every print completion. Reprint / View G-code
  later returned 404 with no log line explaining why; the DB row was
  intact and the archive grid kept showing the entry, but the file
  behind archive.file_path no longer existed on disk.

  Root cause: #1166 added three dispatch sites that cache the live
  archive copy (and library file bytes for Direct-Print) in the shared
  3MF download cache, so /cover could skip a redundant FTP transfer
  mid-print. The cache was originally designed for transient downloads
  under archive_dir/temp/, and clear_3mf_cache(printer_id) — called
  from on_print_complete to keep that temp dir from accumulating —
  happily unlink()'d every cached path. Path.exists() guarded the
  unlink, so no exception, no warning, just silent destruction. Listing
  didn't change; only acting on the archive surfaced the 404.

  Fix: clear_3mf_cache._maybe_unlink refuses to unlink any path outside
  archive_dir/temp. Cache dict is still cleared (so re-cache continues
  to work and /cover hits a fresh path next print), only the on-disk
  delete is gated. Persistent locations — archive/<printer_id>/...,
  archive/unassigned/... (VP-archived prints with printer_id=None),
  library_files/..., is_external library mounts — all survive.

  Regression test test_clear_does_not_delete_persistent_files pins the
  contract end-to-end: archive 3mf, library 3mf, and temp 3mf all
  cached for the same printer; after clear, all three cache entries
  are dropped from the dict, but only the temp file is unlinked from
  disk. Two existing tests updated to put fixtures under
  archive_dir/temp.

maziggy 46c246c504 fix(archive): resume on subtask_id, short-circuit 550, cache 3mf (#972)
Second wave of #972 — reproducer on a 37.5 MB BambuStudio print to an A1
  showed three stacking root causes when Bambuddy restarts mid-print.

  1. Archive start_time lost on container restart. The name-based dedup
     cancelled any "printing" archive older than 4h and recreated it with
     started_at=now(), so a 13h print that saw a restart 10h in ended up
     showing ~1.5h duration. Persist MQTT subtask_id on every archive and
     match on that first, regardless of age — same id means same print,
     resume in place. Also revives Stale-cancelled rows for users
     upgrading mid-print.

  2. 3MF FTP search tried non-existent paths for ~48 min. Order was
     /cache → /model → /data → /data/Metadata → / with 11×30s retries
     each; BambuStudio actually pushes to / on A1, so the real path was
     tested last. Reorder to / first, and raise a new FileNotOnPrinterError
     sentinel from download_to_file on 550 so with_ftp_retry short-circuits
     via non_retry_exceptions. 425 / SSL EOF / connection resets still
     retry as before.

  3. Cover endpoint and archive flow downloaded the same 36 MB twice and
     competed for the printer's single FTP socket, producing 425 errors
     that fed cause-2's retry storm. Add an in-memory _threemf_path_cache
     keyed on (printer_id, normalized filename); whichever flow fetches
     first populates it, the other reuses the file read-only. Eviction
     runs on on_print_complete and deletes the temp file.

  Backend: 14 new tests across test_bambu_ftp.py and a new
  test_subtask_archive_resume.py. Existing suite: 2737 pass. ruff clean,
  frontend build clean.

maziggy 1b43488016 fix(printers): recover large-3mf metadata after FTP timeout (#972)
Two-part root cause for missing photos/filament/cost on large prints
  (#972). The configured ftp_timeout was only plumbed through as the FTP
  socket timeout; the asyncio.wait_for wrapping run_in_executor stayed on
  its 60s hardcoded default, so the user's 300s setting never applied.
  Worse, asyncio.wait_for cannot cancel run_in_executor threads — after
  the 60s outer timeout fired, the executor thread kept running
  ftplib.retrbinary and frequently completed the download ~30–60s later,
  but by then the async wrapper had returned False. with_ftp_retry kept
  re-attempting the same path, each retry truncating the file the zombie
  thread had just written, and the archive was ultimately persisted as a
  fallback with no 3MF.

  download_file_async now accepts timeout at each call site (plumbed from
  ftp_timeout) and salvages post-timeout success via an explicit
  completion flag the executor thread sets only after download_to_file
  returns True. Per-attempt completion dict so a prot_p zombie can't
  flip the flag for a later prot_c attempt. A cosmetic // prefix in the
  directory-search download path is also fixed by replacing string
  concatenation with posixpath.join.

maziggy e4e6e9f8c4 Decouples file uploads and print start commands so that they run in the background asynchronously. When a print is started, the print modal no longer waits for the print to upload and start. Instead, a new toast-based UI appears with the status of prints being dispatched. Prints being dispatched can be cancelled during upload. If cancelled, the partially-uploaded gcode is deleted from the printer automatically before the FTP connection is closed.
This allows users sending particularly large prints to slow printers such as the P1-series to start a print and then move onto another task in Bambuddy immediately (such as starting more prints on more printers). It also gives the user visibility into what's happening instead of a loading indicator appearing for an indefinite period of time.

The new toast-based UI uses websockets to update in real time. It will also appear for other users / instances of Bambuddy, not just the user who started the prints, allowing more transparency and handling cases where the user closes the page and then comes back wanting to know the status of the dispatching.

fix: review fixes for background dispatch PR #408

- Restore missing imports in main.py (inventory, print_log, virtual_printers, mqtt_smart_plug_service)
- Guard voidresp() for A1 printers to prevent hang after upload
- Don't fail upload on voidresp() error since data transfer already completed
- Add ams_mapping to register_expected_print calls for Spoolman usage tracking
- Fix cancel_job TOCTOU race by using single lock acquisition
- Fix batch counter reset TOCTOU by re-checking condition inside second lock
- Add backgroundDispatch translations to fr.ts and pt-BR.ts
- Remove dead upload_progress_callback definitions
- Skip redundant "Print queued" toast in reprint mode (dispatch toast handles it)
- 5 backend tests: cancel_job single-lock TOCTOU, batch reset re-check,
  job lifecycle
- 2 FTP regression tests: voidresp error handling (upload-loop fix),
  A1 model voidresp skip
- 1 frontend test: reprint toast suppression
- CHANGELOG: background dispatch feature + test coverage entries
- README: add background dispatch to Scheduling & Automation
- Website: add feature item to Automation section
- Wiki: add Background Print Dispatch section to print-queue.md

maziggy f9b47282a1 Nozzle-aware AMS mapping for dual-nozzle printers, BL spool detection fix, AMS startup fix, SQLite WAL (#318)
Dual-nozzle H2D/H2D Pro: filament matching now respects nozzle assignments
from the 3MF file. Each AMS unit feeds a specific nozzle (L/R), and the
scheduler/frontend constrain matching to only trays on the correct nozzle.
Falls back to unfiltered matching when no trays exist on the target nozzle.
L/R badges shown in the filament mapping UI. Translated in en/de/ja/it.

Fix AMS slot config overwritten on startup: on_ams_change unconditionally
unlinked BL spool assignments on every MQTT pushall, then re-assigned them
sending ams_filament_setting without setting_id — clearing the printer's
filament preset. Now compares spool RFID identifiers before unlinking.

Fix BL spool detection false positives: removed tray_info_idx from detection
logic in both backend is_bambu_lab_spool() and frontend isBambuLabSpool().
Third-party spools using Bambu generic presets had GF-prefixed tray_info_idx
values, causing misidentification. Now uses only tray_uuid and tag_uid.

SQLite WAL mode with 5s busy timeout reduces "database is locked" errors.

maziggy b886590339 Speed up FTP test suite with class-scoped server fixtures
Function-scoped ftp_server meant 67 TLS server start/stop cycles.
Class-scoped reduces to 10. Adds per-test cleanup fixture to reset
failure injections and filesystem between tests. Isolates
test_disconnect_after_server_gone into its own class to prevent
close_all() from nuking other servers' asyncore sockets.

maziggy f2468077fe Add mock FTPS server and comprehensive FTP test suite (67 tests)
FTP bugs have been the #1 recurring issue across releases (0.1.8+).
This adds a real implicit FTPS mock server and 67 test cases covering
every known failure mode — connection, upload, download, delete, storage
info, model-specific SSL behavior, async wrappers, and failure injection.

New files:
- mock_ftp_server.py: implicit FTPS server on pyftpdlib with failure injection
- conftest.py: FTP test fixtures (certs, server, client factory)
- test_bambu_ftp.py: 67 tests across 10 test classes

Also adds pyOpenSSL to requirements-dev.txt (needed by pyftpdlib
TLS_FTPHandler in the Docker test image).
