feat(enroll): decnet-updater now runs under systemd, not a --daemon fork

Browse Source 
Bootstrap used to end with `decnet updater --daemon` which forks and
detaches — invisible to systemctl, no auto-restart, dies on reboot.
Ships a decnet-updater.service template matching the pattern of the
other units (Restart=on-failure, log to /var/log/decnet/decnet.updater.log,
certs from /etc/decnet/updater, install tree at /opt/decnet), bundles
it alongside agent/forwarder/engine units, and the installer now
`systemctl enable --now`s it when --with-updater is set.
