Merge Main into Belt Printer

Merge origin/main (00429da739) into belt-printer.

Conflicts resolved:
- src/CMakeLists.txt: keep both wxInspector workarounds.
- GCodeProcessor.cpp: keep the belt compare_pos / z_for_height lines.
- PrintObjectSlice.cpp: the belt bbox-Z guard also covers main's
  printable_region_ids bookkeeping.
- TreeSupport.cpp: the belt-floor check runs before main's PendingNode
  queueing.
- Tab.hpp: keep the belt fields, drop the removed upload description
  fields.
- tests/libslic3r/CMakeLists.txt: keep both test files.

Also included:
- eSUN PLA belt presets declare their own filament_id (OFkrxQC4) and
  scripts/filament_id_snapshot.json is regenerated, as main's filament_id
  check requires.
- Custom.json version bumped to 02.04.00.05 so the belt entries reach
  existing installs.
- Fix the ambiguous WithinRel call in the belt apron width test, which
  otherwise breaks the fff_print build.
