fix(viridian): resolve backup system initialization issues
Fix snapper and borgbackup jobs to work with ephemeral-btrfs setup:

Snapper fixes:
- Remove global /.snapshots mount (use nested subvolumes instead)
- Remove unused hostname variable
- Snapshots now stored in .snapshots subvolumes within each service

Borgbackup fixes:
- Add systemd.tmpfiles.rules to create staging directories at boot
- Add readWritePaths for staging directories (systemd sandboxing)
- Staging directories survive ephemeral root wipes

Architecture notes:
- Nested .snapshots subvolumes don't require separate mounts
- systemd tmpfiles ensures directories exist before services start
- ProtectSystem=strict requires explicit ReadWritePaths allowlist
