Upgrade Next.js to 16.4.6 and show locks on latest videos

- Upgrade next and eslint-config-next from 16.3.5 to 16.4.6. The older
  version has critical advisories, which made the Docker build's
  `pnpm audit --audit-level critical` step fail and blocked deploys.
- /api/videos/latest now reports whether the viewer can open each video;
  the dashboard shows a lock and the reason instead of opening the player.
