Fix queue list silent crash and missing uploaded status

Three fixes for queue list not updating:
1. Safe getBlob fallback - works even if old storage.js is cached
   by the service worker (no Storage.getBlob method)
2. Include 'uploaded' status in active filter - photos briefly in
   uploaded state (between upload and verify) were invisible
3. Wrap all interval refreshes in try/catch so one error doesn't
   silently kill all future updates
