Hanif Koh df80c9ae22 Translate H2C Nozzle Rack Filament IDs at the Printer Boundary
The Bambu payload rewrite only matched tray_info_idx, filament_id and
filamentId. The H2C nozzle rack carries filament ids under cate (the auto
nozzle mapping request) and fila_id (the rack status), so the printer got
Orca's OF ids for the filaments and its own ids back for the nozzles in the
same request, and the device tab could not name a rack nozzle's filament.
Add both keys to one shared list used by the rewrite and its pre-check.
