maziggy d196cfc500 fix(virtual-printer): forward H2C rack-swap nozzle pick from slicer to dispatch (#1780) ...

BambuStudio's project_file MQTT command for O1C2 (the H2C dual-
  nozzle-rack variant) carries nozzle_mapping (per-filament physical
  nozzle position IDs) and nozzles_info (per-extruder rack metadata).
  The VP intake was dropping both, so the H2C firmware fell back to
  "last matching nozzle type" auto-pick and ignored the user's
  slicer choice — every HF print landed on R2, every standard print
  landed on R4.

  Carry both fields through the VP intake → queue item → MQTT
  dispatch path. New nullable TEXT columns on print_queue, non-
  branched ALTER (matches ams_mapping / filament_overrides
  precedent). Dual-nozzle gate at start_print() keeps the fields
  off single-nozzle dispatches. Fail-open on malformed JSON —
  firmware auto-picks, never worse than pre-fix.

  Stamps both fields on every plate in the multi-plate Send All
  loop (#1697 / #1188 precedent).

  ams_mapping2 still handles H2D/X2D dual-extruder routing
  unchanged; this fix is scoped to the O1C2 rack-swap mechanism.
