Expose the existing location_ssh.sh key store through the backup CLI:
'backup location ssh-key-set|ssh-key-generate|ssh-key-public|ssh-key-delete <idx>'
(the WebUI runs these as tasks). The locations generator now emits
ssh_key_exists + ssh_public_key (public key only — the private key never
leaves the per-location ssh.key file), so the editor can show the key state.
Also fix the stale SSH_AUTH label (~/.ssh/id_rsa -> managed per-location key).
