feat: Add Borg Backup support to simple LVM backup system

Browse Source 
- Add LV → Borg and VG → Borg backup modes
- GUI: Borg settings panel with repo path, encryption, passphrase
- CLI: Enhanced script with Borg options (--new-repo, --encryption, --passphrase)
- Automatic repository initialization for new repos
- Support for all Borg encryption modes (none, repokey, keyfile)
- Mount snapshots temporarily for file-level Borg backups
- Comprehensive cleanup of snapshots and mount points
- Updated documentation and examples

Benefits:
- Deduplication and compression
- Strong encryption support
- Incremental backups capability
- Space-efficient storage
- Still maintains simple snapshot → backup → cleanup workflow
