not 7a5840149c feat(k8s): Helm chart for the whole stack on a single-node cluster (refs #25)
One chart whose values.yaml is a near-literal transcription of
infra/docker-compose.yml, rendered by three generic templates (Deployment, Job,
Service) over a `workloads` map — so the two stacks can be diffed by eye instead
of by archaeology, and adding a service is a values edit.

Platform-forced deviations, each commented where it appears:
- `args`, never `command`: compose replaces the image CMD, Kubernetes replaces the
  ENTRYPOINT. The chart fails to render on `command`, because the symptom (postgres
  refusing to run as root, Keycloak exec-ing `start-dev`) is nothing like the cause.
- The four Django services apply their own setup_configuration in the web pod
  rather than in a separate init Job: both scripts migrate, and without compose's
  depends_on they race the same database.
- OpenZaak and Objecten are addressed by service FQDN, because Django rejects a
  single-label host in a URL — the reason compose passes container IPs around.
- NodePorts, no ingress; databases are emptyDir until persistence.storageClass is
  set, so the stack comes up on a cluster with no CSI driver.

The upstream config inputs stay in the repo and become ConfigMaps via
infra/helm/seed-configmaps.sh — the Kubernetes sibling of infra/seed-config.sh —
so the compose stack and the chart cannot fork. infra/helm/registry.yaml runs an
in-cluster registry because Talos cannot side-load an image and a laptop-side one
needs a root-level firewall change.

{{ .Chart.Name }} {{ .Chart.Version }} deployed to namespace {{ .Release.Namespace }}.
Watch it converge (the upstream Django services migrate on first boot, so the
first bring-up takes a few minutes):
kubectl -n {{ .Release.Namespace }} get pods -w
kubectl -n {{ .Release.Namespace }} get jobs
Every bootstrap Job must reach Completions 1/1:
{{- range $name, $w := .Values.workloads }}
{{- if and (ne $w.enabled false) $w.job }}
- {{ $name }}
{{- end }}
{{- end }}
Open in a browser (add {{ .Values.host }} to /etc/hosts if you use a name):
{{- range $name, $port := .Values.nodePorts }}
{{- $w := index $.Values.workloads $name }}
{{- if ne $w.enabled false }}
{{ printf "%-16s http://%s:%v" $name $.Values.host $port }}
{{- end }}
{{- end }}

ContainerCreating on a missing ConfigMap, run: make k8s-seed
