    Port Pressure Advance visualization to libvgcode architecture

    Adapt PA visualization (originally in commit e3a7725) to work with
    the new libvgcode library introduced by upstream PR OrcaSlicer#10735.

    Changes across the libvgcode stack:
    - PathVertex: add pressure_advance field
    - Types.hpp: add PressureAdvance to EViewType enum
    - ViewerImpl: add ColorRange, color mapping, range updates for PA
    - LibVGCodeWrapper: pass pressure_advance from MoveVertex to PathVertex

    GCodeViewer UI integration:
    - Add "Pressure Advance" to view type dropdown
    - Add PA color range in legend (3 decimal places)
    - Add PA value display in sequential view marker tooltip
    - Add PA row in position properties table

    The GCodeProcessor PA parsing (M900, M572, SET_PRESSURE_ADVANCE)
    is preserved from the original implementation.

Uruk #1: Single part = center on bed instantly, no GA wasted
Uruk OrcaSlicer#5: Tiny bed (120mm A1 Mini) — halved bed margin from 1mm to
  0.5mm per side to avoid over-shrinking small beds
Also: moved bed dimension vars to function scope for early-exit paths

Remaining Uruk issues (documented, not yet fixed):
- OrcaSlicer#2: Re-arrange doesn't preserve previous positions (by design —
  Snuggle re-nests all selected parts from scratch)
- OrcaSlicer#3: Unit mismatch (inch STLs) — Orca's import handles unit
  conversion before Snuggle sees the mesh
- OrcaSlicer#4: Extreme size ratios — needs adaptive voxel resolution

Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]>

Issue #1 (WRONG): Single-part centering didn't set rotation field.
  Fix: explicit items[0].rotation = 0.0

Issue OrcaSlicer#2 (WRONG/HIGH): Empty voxel grids silently bypassed collision
  detection. Parts with failed voxelization appeared as zero-size
  points that never collided with anything.
  Fix: Empty grids are now detected and marked UNARRANGED before
  reaching the nester. nester_to_item mapping translates indices
  back correctly when writing results.

Also verified NOT breaking (Fellowship consensus):
- Coordinate transforms: all 4 paths correct (Sauron)
- Overflow fallback: std::move safe, excludes is const (Frodo)
- itemid ordering: sort restores correctly after split/recombine
- Division by zero: all guarded
- All-unarranged fallback: equivalent to default arranger

Two data-only fixes:

#1 Strip undefined {if !multicolor_method} wrapper from filament_start_gcode on 110 K2-Plus profiles. The placeholder is a CrealityPrint-ism that survived the profile port; Orca has no such variable, so slicing failed with a hard parser error (reported on Hyper PLA by u/Gullible-Price-4257). Inner per-layer temp logic now runs unconditionally, which is the correct default.

OrcaSlicer#4 Add filament_vendor: [Creality] to 50 Creality Generic profiles missing the field. Without it the UI grouped them under Generic instead of Creality (reported by u/mharrop94).

- Fix OrcaSlicer#1: Combined nozzle_in_extruder_change and filament_in_nozzle_change checks in process_filament_change to prevent double-counting of unload/load times.
- Fix OrcaSlicer#2: Removed get_hotend_change_time() addition in process_filament_change as hotend change time is already accounted for via SYNC gcode.
- Fix OrcaSlicer#3: Added tracking for total_flush_filament_changes statistics.
- Fix OrcaSlicer#4: Passed nozzle_id to process_filament_change to correctly identify the active nozzle under multi-nozzle configuration.

…(Step 2, multi-brand roadmap OrcaSlicer#1)

Devices detail now shows each toolhead for multi-extruder printers
(Snapmaker U1 etc.): T1–T4 with temp/target and loaded filament, marking
the active tool. Parsed from the real U1 /state shape:
- tool 0 = nozzle_temper, tools 1..N = _extra_extruders[] (ordered),
  filament from _sm_filament[], active from _active_extruder.
- Single-nozzle printers fall back to the existing nozzle line.
No dashboard change needed — data already in /api/printers/:id/state.

Build verified: exit 0, launches. (Verified field shapes against the
live U1 state.)
