Coolify's `compose up -d` returns non-zero whenever any sidecar container
hits a `depends_on: condition: service_healthy` timeout. For slow-booting
apps like Twenty (where the worker waits ~3 min for twenty's healthcheck),
this caused apps.create to return started=false even when the primary
stack was running fine.
Now ensureServiceUp probes the host with `docker ps` after a non-zero
compose exit and returns started=true whenever any container is running,
surfacing the compose stderr in startDiag so agents can decide whether
to retry apps.containers.up later.
