Resolve the filament list's printer model from the agent-reported model id or the selected printer profile, so the AMS Materials Setting dropdown and its Confirm button work on OrcaSonar. Third-party trays pre-fill and allow editing their temps, and the popup's initial selection no longer overwrites them.
Render explicitly-empty trays as "Empty" instead of "?" using a wire-derived DevAmsTray::is_empty, while keeping the slot editable.
Hide the flow-dynamics K/N controls for non-Bambu agents — tile, dialog, validation and sends — with Bambu behavior unchanged.
Tests cover model resolution, the K/N gate and empty-tray classification.
