Complete rewrite: Single working LVM block-level backup script

- Removed 40+ broken/messy scripts, moved to old_scripts/
- Created lvm_block_backup.sh - proper block-level LVM snapshot backup
- Uses dd for block-level cloning instead of file-level rsync
- Successfully tested: 462GB backup in 33 minutes
- Creates exact, bootable clone of internal drive to external drive
- Proper LVM snapshot management with cleanup
- Clear documentation in README_BACKUP.md
- Clean, minimal solution that actually works
