anti d2cf1e8b3a feat(updater): sync systemd unit files and daemon-reload on update ...

The bootstrap installer copies etc/systemd/system/*.service into
/etc/systemd/system at enrollment time, but the updater was skipping
that step — a code push could not ship a new unit (e.g. the four
per-host microservices added this session) or change ExecStart on an
existing one. systemctl alone doesn't re-read unit files; daemon-reload
is required.

run_update / run_update_self now call _sync_systemd_units after
rotation: diff each .service file against the live copy, atomically
replace changed ones, then issue a single `systemctl daemon-reload`.
No-op on legacy tarballs that don't ship etc/systemd/system/.
