web(review): switch cause tabs to PhotoGrid, add date-from-path suggestion

- CauseGroupCard now wraps PhotoGrid so selection, keyboard nav, and
  preview flow through the standard timeline plumbing. Per-tile hover
  Approve/Archive and the group-wide Approve all are gone — the bottom
  BulkActionBar's review-section Keep/Archive handle single + bulk.
- Low Resolution tab opts into a new PhotoTile dimensionBadge prop so
  WxH stays visible on each tile.
- New suggestDateFromPath util parses YYYY-MM-DD from filename or
  folder path. RightSidebar surfaces it as an amber Apply row above
  the Taken-at input whenever the photo lacks a trusted TakenAt.
- BulkActionBar gains a "Accept date & Keep" button (review section
  only) that patches each selected photo's TakenAt from its path
  suggestion when available, then approves.
- Drop the Same folder / Same camera / Same year strips and the
  RelatedStrip component from the metadata sidebar.

Also bundles in-progress Notes route + tile components and small
tweaks to LeftSidebar, DuplicatesView, CrossFolderGroupCard, and
photoprism.ts.
