fix: queue stuck on "Busy" for "Any Model" jobs (#435)

When a print was queued with "Any [Model]", the queue widget only
queried items with printer_id=X after dispatch, missing the next
pending model-based item (printer_id IS NULL, target_model="P1S").
The "Clear Plate & Start Next" button never appeared, leaving the
scheduler stuck reporting "Busy".

Add optional target_model query parameter to GET /queue/. When
combined with printer_id, uses OR logic to also return unassigned
items whose target_model matches. The frontend now passes the
printer's model through PrinterQueueWidget to this query.

+- **Queue Stuck on "Busy" for "Any Model" Jobs** ([#435](https://github.com/maziggy/bambuddy/issues/435)) — When a print was queued with "Any [Model]" (e.g., "Any P1S"), it was created with `printer_id=NULL` and `target_model="P1S"`. After the assigned printer finished, the queue widget queried only for items matching `printer_id=X`, missing the next pending model-based item (`printer_id IS NULL`). With no next item found, the "Clear Plate & Start Next" button never appeared, leaving the scheduler stuck reporting "Busy". The queue API now accepts an optional `target_model` parameter; when combined with `printer_id`, it uses OR logic to also return unassigned items whose `target_model` matches the printer's model. The frontend passes the printer's model through to this query.
