Fix v2 gallery not refetching when filter logic operator changes

[gantoine]

Fixes #3798.

In the v2 gallery, filters expose a logic operator (any / all / none) alongside their selection. The "none" operator inverts a filter, e.g. selecting the "Finished" and "100%" statuses with none should show every ROM that is not in those states.

The refetch watcher in GalleryShell.vue only watched the filter selection arrays (selectedStatuses, selectedGenres, ...), not the per-filter *Logic operators. As a result, toggling a filter to its inverse updated the galleryFilter store but never triggered a refetch. The change only took effect when the selection itself was edited, or after a reload (URL hydration re-runs the initial fetch), which matches the report that the inverse "sometimes needs a reload to trigger".

The fetch layer (galleryRoms) already sends statusesLogic and the other operators to the backend, so the query was correct all along; only the client-side refetch trigger was missing.

Fix: watch all *Logic operators alongside their selections in GalleryShell.vue, so inverting a filter (or switching any/all/none) refetches immediately.

v1's FilterDrawer/Base.vue already emits a refetch on logic-toggle, so this was v2-specific.

Greptile Summary

This PR makes v2 gallery results refresh when a filter logic operator changes. The main changes are:

• Adds all per-filter logic operators as reactive store refs.

• Reuses the existing gallery invalidation and metadata fetch flow.

Confidence Score: 5/5

This looks safe to merge.

• All added fields are reactive store refs.
• Every watched operator is included in gallery request construction.
• Existing request guards prevent repeated watcher notifications from starting duplicate metadata fetches.
• No blocking issues found in the changed code.
