feat(backup): implement restore backup functionality

- Added a new component `RestoreBackup` for restoring database backups.
- Integrated the restore functionality with a form to select destination, backup file, and database name.
- Implemented API endpoints for listing backup files and restoring backups with logs.
- Enhanced the `ShowBackups` component to include the `RestoreBackup` option alongside existing backup features.
