Hide unnecessary target model selector on "Any" tab (#528)

When scheduling a print to "Any {model}", a redundant "Target Model"
dropdown appeared even though the G-code is already sliced for a
specific printer model. Changing it would lead to print failures.

Hide the dropdown when slicedForModel is known — the tab label already
communicates the target. The dropdown still appears as a fallback for
legacy files without model metadata.

 ### Fixed
+- **Unnecessary Target Model Selector on "Any" Tab** ([#528](https://github.com/maziggy/bambuddy/issues/528)) — When scheduling a print to "Any {model}", a redundant "Target Model" dropdown appeared even though the G-code is already sliced for a specific printer model. Changing the target model would lead to print failures. The dropdown is now hidden when the sliced model is known (the tab label already shows "Any {model}"). It still appears as a fallback for legacy files without model metadata.
 - **"Clear Plate & Start Next" Button Shown on Printers Without Correct Filament** ([#527](https://github.com/maziggy/bambuddy/issues/527)) — When a print job was queued for "any printer" of a model (e.g., "any H2S"), the "Clear Plate & Start Next" button appeared on ALL printers of that model, including those without the required filament loaded. Clicking it on a printer without the right filament would start a print that fails. The `PrinterQueueWidget` now filters queue items by filament compatibility — it checks the printer's loaded filament types (from AMS and external spools) against the queue item's `required_filament_types` and only shows items the printer can actually print. If no compatible items exist, the widget is hidden.
 - **Manual Spool Weight Overwritten by AMS Auto-Sync** ([#525](https://github.com/maziggy/bambuddy/issues/525)) — When a user manually entered a spool weight (via UI or API), the value was overwritten by the automatic AMS remain% sync that runs on every MQTT update. The AMS remain% is integer-only (~10g resolution for 1kg spool) and can't match precise manual entries. Added a `weight_locked` flag that is automatically set when `weight_used` is explicitly updated via the API. Locked spools are skipped by both the automatic AMS remain% sync and the manual force-sync endpoint. The usage tracker (3MF/gcode delta tracking) is unaffected. Users can re-enable AMS sync by setting `weight_locked: false`.
 - **Inconsistent Print Cost on Reprints** ([#505](https://github.com/maziggy/bambuddy/issues/505)) — Reprinting the same model produced different costs each time (e.g., £0.77, £1.54, £2.03 for the same print). Three independent code paths wrote to `archive.cost` with conflicting strategies: the usage tracker summed ALL historical `SpoolUsageHistory` rows for the archive (including rows from previous reprints), and a separate `add_reprint_cost` method added yet another full print's cost on top. Removed the redundant `add_reprint_cost` path entirely and changed the usage tracker to compute cost only from the current print session's results instead of querying all historical rows. `archive.cost` now always reflects the cost of a single print.
