Fix video autoplay reliability, add shuffle playback, refresh data on appear

- Remove cache expiry on video feed (fetch once, keep for session)
- Add retry logic (3 attempts with backoff) for autoplay resolution
- Replace random video selection with shuffle-bag (no repeats until all played)
- Reload games every time DashboardView appears
- Cache standings per day to avoid redundant fetches
