cleanup: Archive old complex scripts and documentation

- Move all old complex backup scripts to old_scripts/
- Archive previous documentation versions
- Clean up temporary files and debian packages
- Update README to focus on new simple system
- Keep only the enhanced simple backup system in main directory

Main directory now contains only:
- simple_backup_gui.py (GUI interface)
- enhanced_simple_backup.sh (CLI interface)
- list_drives.sh (helper)
- simple_backup.sh (basic CLI)
- SIMPLE_BACKUP_README.md (detailed docs)
- README.md (project overview)
