fix: bulk label apply, instant archive removal, per-photo state, drop sidebar counts

Issue 1 — colors/labels not applying in bulk:
- sidecar validColors only accepted 4 of the 8 UI swatches, so teal/blue/
  purple/pink returned "invalid color" and rolled back the whole bulk txn.
  Add teal, blue, purple, pink to validColors.
- Add invalidateFacets() and call it on the success path of bulk marks,
  patchTargets, and single-photo edits so the Colors/Ratings/Notes facet
  sections refresh immediately instead of waiting out staleTime.

Issue 2 — archived photos linger in the grid:
- Add a UI-only removedIds set to the bulkAction store; archive/delete/
  restore/keep call markRemoved() on success so tiles vanish instantly,
  cleared once the server-reconcile refetch lands (no cache eviction).

Issue 3 — per-photo progress state:
- Wire startBulk/doneBulk/failBulk into all metadata applies, bulk
  (BulkMetadataSidebar) and single (RightSidebar), so colors/ratings/
  notes/dates/keywords show the spinner -> check -> X overlay.

Issue 4 — remove Left-sidebar count badges:
- Drop count badges from root folder, Archive, heaps, Notes, and the
  folder tree, plus the now-dead count queries and unused imports. Facet
  drill-panel counts are unchanged.
