Fix: correct axis-remap G-code emission and belt first-layer travel speed (B2, B3)

Browse Source 
- BeltGCodeWriter::travel_to_xyz final branch used config.travel_speed
  instead of the computed first-layer-aware travel_speed.
- extrude_to_xyz decided emit_xyz vs emit_xy from pre-remap Z; emit full
  XYZ whenever an axis remap is active so remapped machine-Z is never
  dropped.
- base travel_to_xyz now applies apply_axis_remap() on all emitted
  destinations (standalone remap on non-belt printers was unremapped).
- spiral/arc travels fall back to normal linear lift under active remap
  (endpoint-only remap can't preserve arc plane/I-J).
- set_axis_remap() is now synced unconditionally each export to avoid a
  reused writer retaining a stale non-identity mapping.
