fix: tile overlay reactivity + facets showing all marked/noted photos

Problem 1 — per-photo progress overlay never rendered on the grid:
- bulkPhotoStates was `$state(new Map())`; a `.get(uid)` read in PhotoTile
  didn't reliably re-run when the entry flipped, so the spinner/check/X
  overlay never appeared. Switch to SvelteMap (svelte/reactivity).

Problem 2 — Notes / Colors / Ratings only showed the newest ~1000 photos:
- All three derived from `listPhotos({ count: 1000 })`, silently hiding
  older marked/noted photos.
- listPhotosWithNotes now pages the whole library.
- Add listPhotosByUids() and resolve the Colors/Ratings marks-pool from the
  complete marked-UID set (from getAllMarks) instead of the newest slice;
  wire it into the TagsBrowserSidebar panel and the tag drill page.
