Two bugs caused spool assignments to always configure AMS slots with
generic Bambu filament IDs (e.g. GFB99 "Generic ABS") instead of the
spool's actual slicer preset:
1. PFUS* IDs (cloud-synced custom presets) were blanket-rejected and
replaced with generic IDs in both assign_spool and configure_ams_slot
2. Generic fallback IDs (GFB99, GFL99, etc.) were treated as "good"
presets by the slot-reuse logic, making them sticky once set
New priority: spool's own slicer_filament > slot's non-generic preset
(same material) > generic fallback.
