Zitadel: run init and setup in the foreground

start-from-init ran in the background with its output thrown away, and the PID to kill was guessed from lsof after 60 seconds; when the process had already ended, kill got no PID and failed with exit 2. init and setup finish on their own, report their errors, and the service only starts once its user exists.
