installLibrePortalWebUITaskService only wrote the unit if it didn't already
exist, so env/User/mode changes never reached an existing install and a
docker-type switch couldn't update the service. Make it converge: compute the
desired unit for the current mode and only rewrite + daemon-reload + restart
when it actually differs (otherwise just ensure enabled+running, no restart, so
routine re-runs don't bounce the processor and kill in-flight tasks). The
docker-type switcher now calls this idempotent setup (replacing the one-shot
restart helper), so a swap updates the env AND restarts in one step.
