Replace LISTEN_ADDR (pod IP) with POD_DNS_NAME (DNS FQDN) for Patroni
REST API and PostgreSQL connect addresses to enable stable addressing
across pod restarts.
Changes:
- Add POD_NAME, HEADLESS_SERVICE, and POD_DNS_NAME environment variables
to Patroni StatefulSet pods
- Create patroni-headless Service for DNS-based pod discovery
- Update patroni.config.yaml to use ${POD_DNS_NAME} for pod_ip,
connect_address (PostgreSQL), and connect_address (REST API)
- Register patroni-headless service creation in reconciler
Reasons:
- Pod IPs are ephemeral and change on restarts, causing connection issues
- DNS names (pod-name.service.namespace.svc.cluster.local) are stable
- Improves reliability of Patroni DCS registration and cluster communication
- Aligns with Kubernetes best practices for StatefulSet networking

The PR adds helmfile configuration which deploys pgskipper and a sample application to verify connectivity and failover behavior.
