maziggy d5153f1de3 feat(slicer): live progress + filament discovery polish + OrcaSlicer warning
End-to-end live progress, two correctness fixes, and a UX warning around
  the upstream OrcaSlicer bugs we discovered while testing.

  LIVE PROGRESS
  =============

  Wire OrcaSlicer / BambuStudio's --pipe progress channel through the
  sidecar -> Bambuddy -> persistent toast so a user-initiated slice shows
  "{name} -- Generating G-code (75%) -- 47s" instead of just elapsed time.
  The same wiring covers the SliceModal's filament-analysis preview slice
  (the real slice that fires before profile picking, used to discover
  which AMS slots an unsliced plate consumes) and the embedded-settings
  fallback path triggered by Orca's --load-settings segfault on complex
  H2D models.

  - Sidecar (orca-slicer-api/bambuddy/profile-resolver, separate commit):
    switch /slice from execFile to spawn, mkfifo per request, parse the
    CLI's structured JSON progress events into a per-process
    ProgressStore, expose GET /slice/progress/:requestId.
  - Bambuddy backend: slicer_api.slice_with_profiles + slice_without_profiles
    accept request_id + on_progress, spawn a 1Hz parallel poller that
    forwards each snapshot via SliceDispatchService.set_progress(job_id,
    ...) onto the matching SliceJob; GET /slice-jobs/:id includes the
    latest snapshot on every poll. The 404 from the early-race window
    (POST fired before sidecar's progressStore.start) is treated as a
    retry rather than terminal -- otherwise the poller bailed before any
    progress could ever arrive.
  - /api/v1/slicer/preview-progress/:requestId proxies the sidecar's
    progress endpoint for the modal's filament-discovery flow (the
    /filament-requirements call is server-originated; the browser can't
    reach the sidecar directly).
  - Frontend: SliceJobTrackerContext re-renders the persistent toast with
    the new format when a useful progress frame is present, falls back
    to elapsed-time-only when the sidecar hasn't emitted yet or doesn't
    support progress. SliceModal.FilamentAnalysisSpinner generates a
    per-(source, plate) UUID, polls the proxy at 1Hz, and mirrors the
    inline spinner contents into a separate persistent toast so the
    preview slice doesn't feel silent either.

  CORRECTNESS FIXES
  =================

  - MakerWorld imports were persisting URL-encoded filenames verbatim
    ("stormtrooper-helmet%20h2d.3mf"). Backend now urllib.parse.unquote
    s the manifest-supplied name and the URL path-tail fallback before
    passing to save_3mf_bytes_to_library; frontend defensively
    decodeURIComponent s in the slice toast / analysis spinner so
    already-imported rows display cleanly without a backfill migration.
  - The fallback path's slice_without_profiles call now forwards the
    same request_id + on_progress as the primary slice_with_profiles
    call so the toast keeps updating across the segfault -> embedded-
    settings retry boundary instead of going blank.

  ORCASLICER WARNING
  ==================

  Verified two upstream OrcaSlicer CLI bugs reproduce on the latest
  nightly (2.4.0-dev, 2026-04-28) with the help of an isolated AppImage
  extract and a minimal sentinel-value-injected cube fixture:
    - OrcaSlicer/OrcaSlicer#12426 -- SIGSEGV in
      update_values_to_printer_extruders_for_multiple_filaments on
      painted multi-extruder 3MFs (commented on the existing thread,
      not a new issue)
    - OrcaSlicer/OrcaSlicer#13386 -- CLI strict-validates parameter
      values BambuStudio writes by default (solid_infill_filament: 0,
      tree_support_wall_count: -1, prime_tower_brim_width: -1) and
      rejects with exit 238, even though Orca's own GUI tolerates
      them (filed by us alongside this change)

  Settings -> Workflow -> Slicer card renders an amber inline warning
  under the preferred-slicer dropdown when orcaslicer is selected,
  linking both upstream issues and recommending BambuStudio until the
  fixes land. Option stays pickable -- users who only slice STLs aren't
  affected by either bug.
