Client accept/reject votes with keyboard-driven culling

- verdicts table (per link, like ratings), PUT verdict endpoint, typed Verdict enum
- share page: thumbs up/down, verdict filter with counts, view-scoped selection bar
- lightbox: per-page shortcut table (P/X/U, 1-5/0, S), ? help overlay, action
  toast when a keyboard vote auto-advances
- shared useLightbox hook; single keydown subscription reading live state via ref
- album view: per-link thumbs and vote counts; share list shows accept/reject totals
- feedback queries deduped and run concurrently; verdict counts in one scan
