Merge upstream/main into iXex PR branch (#13086)

Catches the iXex/IDEX parallel-printing branch up to upstream main
(102 commits). Two content conflicts resolved:

- src/libslic3r/Preset.cpp: s_Preset_printer_options — kept upstream's
  new "use_3mf" key and our iMEX printer-capability/mode keys.
- tests/fff_print/test_gcodewriter.cpp: upstream revived the disabled
  suite (#14196), dropping the obsolete [.]-tagged lift() test and its
  config_lift_unlift.ini; kept their set_speed + z_hop tests and appended
  our 10 per-firmware set_pressure_advance/set_temperature scenarios.

+AppImages are published for both **x86_64** and **aarch64** (ARM64). Pick the file matching your CPU — the ARM64 build has `aarch64` in its name (e.g. `OrcaSlicer_Linux_AppImage_Ubuntu2404_aarch64_*.AppImage`).

  1. Download App image from the [releases page](https://github.com/OrcaSlicer/OrcaSlicer/releases).
