librelad e5f637bca6 refactor(service): make task processor service setup idempotent
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.

# LibrePortal Task Processor Systemd Service Setup
# Replaces crontabSetupTaskProcessor with systemd service.
#
# Idempotent: computes the desired unit for the CURRENT docker mode and only
# rewrites + daemon-reloads + restarts when it actually differs from what's on
# disk. So routine re-runs are no-ops (no needless restart that would kill an
# in-flight task), while a rooted<->rootless switch — which changes the env
# block — triggers exactly one rewrite + restart so the processor re-reads the
# new mode. Safe to call from install AND from the docker-type switcher.
