fix(backup): allow manual backups when automated backups are disabled

- Manual backup button now works regardless of backup_enabled setting
- backup_enabled only controls scheduled/automated backups
- Manual backups only require destination to be configured
- Fixed backup_type to correctly show 'manual' vs 'scheduled'
