feat(diagnostic): add "Store sent files on external storage" check (install step 4)

Detects the printer-side variant of install step 4 — many users (esp. on
  clean installs) forget to enable this and only notice when their archive
  cards have no thumbnails. The diagnostic now catches it upfront.

  Detection: read state.store_to_sdcard, which Bambuddy already parses from
  MQTT push_status home_flag bit 11 (bambu_mqtt.py:153). Instant, no I/O.

  An FTP upload-and-verify probe was tried first and rejected. /cache is
  always writable from Bambuddy regardless of the slicer setting — only
  BambuStudio's own behaviour changes when the toggle flips, not the
  printer's acceptance policy. Confirmed empirically against X1C + H2D
  with the slicer option toggled off: probe succeeded, home_flag bit 11
  stayed True. So the only reliable signal is what the printer actually
  reports about its own state.

  Limitation: the printer-side variant only exists on newer firmware
  (P2S 01.02 / Bambu Studio 2.6+). On older versions the toggle lives
  only in the slicer and the printer never hears about it, so this check
  will pass even when the user is missing step 4 in BambuStudio. The
  skip-text and the wiki call this out explicitly. A reactive banner on
  the no-3MF archive-fallback path is planned as a follow-up to cover
  that case.

  Statuses:
  - pass:  state.store_to_sdcard is True
  - fail:  state.store_to_sdcard is False (-> overall escalates to problems)
  - skip:  no live state, disconnected, or field never populated

 ### Added
+- **Connection diagnostic now verifies install step 4 ("Store sent files on external storage")** — Many users miss this setting when adding their first printer; without it BambuStudio / OrcaSlicer never leave a `.gcode.3mf` on the printer's SD card, every archived print falls back to no-thumbnail / no-metadata, and the cause is invisible until the user notices the archive is empty. **The trap with detecting this**: on newer firmware (P2S 01.02 / Bambu Studio 2.6+) the toggle moved onto the printer itself and is pushed on MQTT `home_flag` bit 11 (Bambuddy already parses this into `state.store_to_sdcard`). On older versions it's a purely slicer-side preference invisible to the printer. An FTP upload-probe approach was tried first — it always passed regardless of the slicer toggle because the `/cache` directory is always writable from Bambuddy's perspective; the slicer toggle only controls what BambuStudio chooses to do, not what the printer accepts from other clients. Confirmed empirically against an X1C + H2D with the slicer option toggled off (probe still succeeded, `home_flag` bit 11 stayed True). **Fix**: new `external_storage` check reads `state.store_to_sdcard` directly. Pass when the printer reports the bit on, fail when off, skip when no live MQTT state or the field has never been populated (older firmware that doesn't push `home_flag`). Localised fix-text points at install step 4 with both the printer-side and slicer-side variants spelled out; the `skip` text explicitly calls out the older-slicer limitation so users on that path know to verify manually. Slot in the check list sits between `port_ftps` and `mqtt_auth`. 5 new tests (`TestExternalStorageCheck`) cover pass-on-true, fail-on-false, skip-on-disconnect, skip-on-pre-add (no state), skip-on-missing-field. The reactive symptom-side detection — a one-time banner the first time the archiver records `extra_data.no_3mf_available=True` after a slicer-initiated print — is planned as a separate follow-up to cover the slicer-only setting case. Wiki updated on the System page (`features/system-info.md`) and the Troubleshooting page (`reference/troubleshooting.md`). i18n: 4 new keys (title, pass, fail, skip) localised to all 11 locales (de, en, es, fr, it, ja, ko, pt-BR, tr, zh-CN, zh-TW) — no English fallbacks.
+
 - **"Open in Slicer" desktop target is now configurable separately from the API sidecar slicer (#1329, reported by @hasmar04)** — Reporter wanted to slice via the Bambu Studio sidecar but open files locally in OrcaSlicer; the existing `preferred_slicer` setting drove both, so picking one forced the other. The slicer-URI flow on Workflow → Slicer literally swapped the BambuStudio handler for the OrcaSlicer one whenever the user switched the API choice. **Fix: new `open_in_slicer` setting** (`'bambu_studio' | 'orcaslicer' | null`) drives only the desktop "Open in Slicer" URI handoff; the in-app SliceModal + sidecar URL routing in `library.py`, `archives.py`, `slicer_presets.py` continue to use `preferred_slicer` exactly as before. Default is `null` — the frontend falls back to `preferred_slicer` so existing installs behave identically until a user changes it (no migration, no churn). **Storage** lives in the existing `app_settings` key/value table; the PUT path serialises a Python None as the literal string `"None"`, and the GET path normalises it back via a new branch in `_build_settings_response` matching the existing `default_printer_id` convention — without that normalization the frontend can't tell "explicit override absent" from "explicit override set to a bogus value". **Frontend**: Settings → Slicer card relabels the existing dropdown's description ("Slicer used for in-app slicing via the API sidecar"), adds a new "Open in Slicer" dropdown below it with three options — "Same as API slicer" (the inherit-from-preferred default), "Bambu Studio", "OrcaSlicer". `ArchivesPage` (5 `openInSlicerWithToken` call sites), `MakerworldPage` (the URI handoff branch when `useSlicerApi=false`), and `ModelViewerModal` (4 `openInSlicer(...)` call sites) all switched from reading `settings?.preferred_slicer` to `settings?.open_in_slicer ?? settings?.preferred_slicer`. MakerworldPage's "Slice in {{slicer}}" button label additionally branches on `useSlicerApi`: when on, the label reflects the API slicer; when off, the desktop slicer — so the button text always matches what the button actually does. The OrcaSlicer "known CLI bugs" warning stays attached to the API dropdown (where it belongs — it's about the sidecar's CLI). **i18n**: 3 new keys in all 11 locales (de/en/es/fr/it/ja/ko/pt-BR/tr/zh-CN/zh-TW) — `settings.openInSlicerLabel`, `settings.openInSlicerInherit`, `settings.openInSlicerDescription` — plus an updated `settings.preferredSlicerDescription` everywhere (the old wording "Choose which slicer application to open files with" became wrong once the field stopped driving the desktop handoff). No English fallbacks per the project's hard rule. **Tests**: 3 new in `TestOpenInSlicerOverride` pin the contract — default is null, override persists across GET, explicit reset to null round-trips correctly without leaving the `"None"` string leak. Full backend suite green (5798/5798); frontend ESLint + build clean; vitest on SettingsPage + MakerworldPage 48/48 green; i18n parity 5095 leaves × 11 locales green.
 
 - **Queue items + Print modal now show the build plate type, per-plate accurate (#1281, reported by @CMW-ISS)** — Reporter on a multi-printer farm with 40+-plate runs needed to walk to the printer with the right physical plate; the archive card had recently grown a bed-type badge, but the queue and the scheduling modal didn't. They were having to open the source 3MF in the slicer to look up which plate each queued / scheduled job needs. **Backend**: new `extract_bed_type_from_3mf(file_path, plate_id)` helper in `utils/threemf_tools.py`, alongside the existing `extract_filament_usage_from_3mf` shape — reads `Metadata/slice_info.config`, finds the `<plate>` with the matching `index`, returns its `curr_bed_type`. When `plate_id` is None it returns the first plate's value (matches the archive-level capture convention). `PrintQueueItemResponse` gains a `bed_type: str | None` field; `_enrich_response` populates it from `archive.bed_type` / `library_file.file_metadata["bed_type"]` as the file-level default, then overrides per-plate via the new helper when `item.plate_id` is set. This matters because `archive.bed_type` is captured at ingest as the FIRST plate's value only (see `services/archive.py:235`) — a 40-plate 3MF mixing PEI + Engineering returns "PEI" for every plate at the archive level, even though the user's plate 17 actually needs Engineering. The per-plate override re-reads the 3MF and returns the truth. **`/archives/{id}/plates`** (and the library-file equivalent) now include `bed_type` in each plate object so the PrintModal's plate selector can render the badge inline. **Frontend**: queue card meta row gains a bed badge after filament weight — uses the existing `getBedTypeInfo(bed_type)` helper from `utils/bedType.ts` (the same one the archive card uses, so all 11 canonical bed labels + icons are covered including the BambuStudio / OrcaSlicer spelling drift). PrintModal's per-plate `PlateSelector` shows the bed badge under each plate's filament line; the modal header carries a bed badge for the selected (or sole) plate, surfaced before the user hits Schedule. `PlateInfo` + `PlateMetadata` types both get an optional `bed_type` field. No new i18n keys needed — `getBedTypeInfo` returns the canonical English plate name as the human label, matching the archive card's existing convention. **Tests**: 8 new unit cases in `test_threemf_tools.py::TestExtractBedTypeFrom3mf` pin the helper (single-plate, multi-plate per-plate, no-plate-id defaults to first, unknown-plate-id → None, plate-without-bed-type → None (no fall-through to another plate's value), missing slice_info, invalid file, whitespace trim). Full backend suite green (3848/3848); frontend build clean; ESLint clean; vitest on touched pages 81/81; i18n parity 5092 leaves × 11 locales green.
