Fix backup script: tar.gz output, lockfile, correct log path, install at /usr/local/bin

- Renamed output to jarvis_backup_TIMESTAMP.tar.gz (admin panel pattern)
- Log now goes to /var/backups/jarvis/backup.log (admin panel reads this)
- Lockfile at /var/backups/jarvis/backup.lock (prevents concurrent runs)
- tmpdir + trap cleanup for safe temp handling
- Install at /usr/local/bin/jarvis-backup.sh (admin panel trigger path)
