feat: implement backup management features

- Added `createBackupAction`, `verifyDatabaseAction`, and `refreshBackupStatsAction` for handling backup operations.
- Introduced `getBackupStats` method in `BackupClient` to retrieve daily backup statistics.
- Updated API route to support fetching backup stats.
- Integrated backup stats into the `BackupSettingsPage` and visualized them with `BackupTimelineChart`.
- Enhanced `BackupSettingsPageClient` to manage backup stats and actions more effectively.
