maziggy 4686d108ef feat(slice): cross-printer re-slicing across nozzle classes + multi-plate slice-all ...

Re-slicing a 3MF authored for a single-nozzle printer (X1C, P1S, A1, P2S)
  onto a dual-nozzle printer (H2D / H2D Pro) — or vice versa — previously
  failed with "G-code in unprintable area of multi-extruder printers" (the
  source's bed-coordinate layout lands in the H2D's per-nozzle dead zone)
  or, on multi-color projects, a hard SIGSEGV inside the slicer's ZFiller
  polygon-clipping. Earlier shipped a fail-fast 400 guard; this drop lifts
  it and actually does the conversion by forwarding the sidecar's existing
  --arrange flag when the source and target nozzle classes differ. BS
  itself reconciles the embedded project_settings.config against the new
  printer that way, the same way the GUI's "Switch Printer" operation
  does. The guard becomes a kept-for-compat no-op.

  Slice-all-plates added to the SliceModal: a checkbox for multi-plate
  sources sends plate=0 to the backend, which forwards --slice 0 to the
  BS CLI. Same-class slice-all produces one multi-plate output 3MF in a
  single sidecar call. Cross-class slice-all loops per plate (BS's
  --arrange is project-wide and would otherwise consolidate every plate's
  objects onto one bed) and merges the per-plate outputs into one
  multi-plate 3MF locally via the new merge_plate_3mfs helper. The toast
  shows "Plate 2 of 5 — Generating G-code (47%)" through the loop.

  Three side fixes surfaced during testing:
  - substitute_unused_plate_filaments overwrites unused-slot filaments
    with the slot-1 selection before slicing so BS's loaded-filament
    temperature validator doesn't reject a PLA print whose unused slot 2
    defaulted to ABS in the dropdown
  - re-sliced archive thumbnail now prefers the source's per-plate
    render (Metadata/plate_N.png) over the project-wide MakerWorld cover
    art, because BS CLI with --arrange skips writing a fresh per-plate
    preview
  - re-sliced archive bed_type now lifts from the sliced output's
    curr_bed_type onto the PrintArchive column the card actually reads

  Schema: SliceRequest.plate range relaxed from ge=1 to ge=0 to admit
  the "all plates" sentinel; SlicerApiService.slice_with_profiles /
  slice_with_bundle take an `arrange` parameter.

  Tests: 26 in test_slicer_3mf_convert (count / merge / substitute /
  extract), 3 in test_slicer_api (arrange wire format), 9 in
  test_library_slice_api (guard no-op, bed_type lift, thumbnail
  fallback, new cross-class slice-all loop integration test), 2 in
  test_archive_service (Auxiliaries fallback), 4 in SliceModal.test
  (plate=0 toggle), 2 in SliceJobTrackerContext.test (multi-plate toast
  prefix). 659 backend + 42 frontend green; backend ruff clean,
  frontend build clean, i18n parity green at 4984 keys × 9 locales.
