maziggy 7596725550 fix(mqtt): external-spool ams_filament_setting must use global tray_id (#1279)
ams_set_filament_setting and reset_ams_slot encoded the single-external
  case as {ams_id: 255, tray_id: 0, slot_id: 0}. The "LOCAL tray_id = 0"
  comment was a misread of the printer's response (which echoes the local
  slot position), not the request semantics.

  Captured BambuStudio -> X1C exchange shows the request encoding is
  {ams_id: 255, tray_id: 254, slot_id: 0} (global tray index in tray_id).
  The previous code's tray_id: 0 is what the P1S in #1279 rejects with
  result: "fail", which silently broke external-spool filament selection
  on every Bambu printer with no AMS or external spool in active use.

  Dual-external (H2D) branch was not in the captured exchange and is
  explicitly pinned at the legacy encoding pending a Studio -> H2D capture.
