When a user creates a new filament preset by inheriting from an
existing one (e.g., "Brand ABS @BBL H2D" inheriting from "Generic
ABS @BBL H2D"), the resulting preset previously had no filament_id
of its own. This caused two problems:
1. The AMS sync pipeline could not distinguish the user preset from
its parent, so syncing filaments from the printer always resolved
to the generic base preset instead of the user's custom one.
2. External tools that rely on filament_id for preset identification
(e.g., Bambuddy, see maziggy/bambuddy#1053) could not assign or
recognize user-created inherited presets in AMS slots.
The root cause was twofold:
- No filament_id was generated during save_current_preset() for
inherited filament presets. Only base (non-inheriting) presets
received one via the CreatePresetsDialog flow.
- The AMS matching logic in sync_ams_list(), get_ams_cobox_infos(),
and get_filament_presets() filtered candidates with
`get_preset_base(f) == &f`, which by definition excludes any
preset with a non-empty inherits() field.
This commit:
- Generates a unique filament_id (MD5 hash of preset name, prefixed
with "P", truncated to 8 chars) when creating a new filament
preset in PresetCollection::save_current_preset(). This matches
the existing ID generation scheme used for base filaments in
CreatePresetsDialog::get_filament_id().
- Persists filament_id into the JSON when saving inherited presets
via Preset::save() and get_differed_values_to_update().
- Broadens the AMS filament matching predicates to also consider
user presets that carry their own filament_id, rather than
requiring them to be base presets.
