- Add left sidebar filter panel to MixedView and GamesView with name
search and tag toggles; only shows tags/categories used in the current
library; AND logic when multiple tags are selected
- Add GET /api/tags/library-assignments endpoint returning all tag
assignments for a library keyed by mediaKey
- Add getTagAssignmentsForLibrary() and getTagsSortedByUsage() to tags lib
- Support ?sort=usage on GET /api/tags/items to order by assignment count
- Tag selector: per-category search, top-25-by-usage display, inline add
tag (auto-assigned to current item) and add category flows
- Tag selector: group assigned tags by category into nested pills
- Fix nested <button> hydration error in EntryTile (outer element is now
a div with role="button")
- Keep filter panel assignments in sync when tags are toggled or created

Assigned tags now render as a single outer pill per category containing
smaller inner tag pills, instead of one pill per tag with a repeated
category prefix.
