Claude bc357d2efd Overhaul backup system: rsync for local, rclone for encrypted cloud 
Major changes:
- Local backup uses rsync exclusively with support for 1-4 drives
- Drive names are now customizable (default: primary, backup1, etc.)
- Added separate cloud backup option with rclone + encryption
- Guided setup for Google Drive and OneDrive with encryption
- rclone.conf auto-backed up to all local drives
- Added off-site backup guidance (Signal, Box.com, password managers)
- Removed old rsync/rclone choice and full/split modes

Documentation updates:
- Explain why fail2ban provides no benefit with key-only SSH
- Explain why rsync instead of RAID
- Document rclone.conf decryption and restore process
- Update all backup-related sections for new structure
