The delegation nginx serves the .well-known documents from an nginx.conf that
is rendered from ingress.domain and mounted with subPath. Changing the domain
rewrote the ConfigMap but left the running pod untouched: the pod template was
unchanged, so nothing rolled, and the kubelet never refreshes a subPath mount.
The pod kept serving the old delegation while looking perfectly healthy - the
failure mode from #82.
The pod template now carries checksum/config over the rendered delegation
ConfigMap, so a changed nginx.conf rolls the deployment.
Also documents the limit that remains for homeserver.yaml: it comes from a
1Password-backed Secret, whose content Helm never sees, and the operator's own
auto-restart only ever covers Deployments - not this StatefulSet. That case
needs a manual rollout restart, which the values.yaml now says out loud.
Major bump: runtime behavior changes - a delegation config change now costs a
restart of the nginx pod (a few seconds, no persistent state).
