[Bug fix] Update error & About bundle download

- Data for Arcaea 5.8.0
- Fix a bug that the server's database updates from an old version may meet a challenge if `recent30` table has some strange data.
- Fix the issue where the bundle downloading memory cache does not clean up.
- Add a config term to only change the X-Accel-Redirect prefix for bundle downloading.
