Batch tag photos faster with one apply button

Commit room, phases, and condition in one go. Lock markers show which photos are owned by contents.

What's New

Batch tagging is now faster: the Apply button commits everything at once — room, phases, and salvageable status — instead of two separate apply actions. The salvageable toggle matches the one in the lightbox for consistency.

When a salvageable change is staged, contents-owned photos (linked items managed by the contents phase) now display a lock marker in the grid so you see exactly which selected photos won't be updated. A toolbar badge counts the skipped photos with a tooltip explaining why.
