feat(install): updates refresh systemd units; new installs run the newest release (#729)

Updates that move HEAD now install changed systemd units through a root-owned helper (/usr/local/sbin/ledmatrix-refresh-units, two literal sudo lines), with a backup restored on rollback; a refresh that fails part-way puts the old units back. Devices without the new sudo rule keep updating and are told to re-run the installer once. The one-shot installer now checks out the newest vX.Y.Z release (LEDMATRIX_CHANNEL=beta keeps main) and never moves an existing checkout backwards.
