maziggy c1f69ee0cc fix(slicer): wrong-printer slicing + sliced-archive filament list + per-instance MakerWorld compat
Five stacked slice-pipeline bugs that each made the modal's profile picker
  theatrical for 3MF inputs:

  (1) `_strip_3mf_embedded_settings` removed `model_settings.config` /
      `slice_info.config` / `cut_information.xml` along with
      `project_settings.config`. The CLI silently exited after
      "Initializing StaticPrintConfigs" — exit 0, no result.json — and
      Bambuddy masked the failure by re-running with embedded settings
      and the source's bound printer. Strip removed from the dispatch
      path entirely.

  (2) Standard-tier preset stubs lacked the `type` field, so the CLI
      rejected `--load-settings` with rc=-5 ("input preset file is
      invalid") and the same masking fallback fired. Added
      `_SLOT_TO_PROFILE_TYPE` so each stub carries the right
      machine/process/filament discriminator.

  (3) Sliced-archive cards listed every project-wide AMS slot (16+
      swatches for a 2-color print). `slice_and_persist_as_archive` now
      reads `filament_type` / `filament_color` from the sliced output's
      `slice_info.config` (which `ThreeMFParser` already gates on
      `used_g > 0`) instead of inheriting from the source archive.

  (4) SliceModal had no warning when the picked printer profile didn't
      match the source 3MF — the CLI rejects cross-printer slices
      (rc=-16) and fell back to embedded settings, producing wrong-printer
      g-code that errored at print dispatch. Plates response now exposes
      `source_printer_model`; the modal compares against the picked
      profile name and disables Slice + shows an inline warning on
      mismatch.

  (5) MakerWorld URL-paste resolver listed plate instances without
      showing which printer each was sliced for (`/instances/hits`
      omits compatibility info that lives on `design.instances[]
      .extention.modelInfo`). The resolve route now joins both payloads
      by instance ID and forwards `compatibility` + `otherCompatibility`
      onto each hit; the MakerWorld page renders "Sliced for {primary}"
      + "Also marked compatible: ..." per row.

  Tests: 6 unit tests for `extract_source_printer_model_from_3mf`, 1 for
  filtered filament metadata via ThreeMFParser, 2 for makerworld resolve
  compat-merge (happy path + missing modelInfo), 3 frontend SliceModal
  tests for the printer-mismatch warning + Slice-disabled gate. New i18n
  keys `slice.printerMismatch`, `makerworld.slicedFor`,
  `makerworld.alsoCompatible` across all 8 locales.
