Per the approved plan (jiggly-snacking-iverson.md, 'GitLab True Cross-Site Replication' section) - replacing the git-mirror CronJob with real CNPG streaming replication for pg-gitlab and pg-praefect, reusing the exact pattern already proven for pg-authentik. This commit is network plumbing only, no DB replication yet: - Repoint both CNPG clusters' barmanObjectStore backup target from in-cluster gitlab-minio-svc to VPS MinIO (also becomes the initial seed source for the VPS's replicas in Phase 1c). - New ha-gitlab-postgres/ha-praefect-postgres NodePort Services (bypass CNPG's own -rw Services) on both home and VPS. - New PeerAuthentication with portLevelMtls PERMISSIVE on the replication ports - ambient mesh STRICT default would otherwise reset the VPS/witness's connection before the Postgres TLS handshake starts. - Extended allow-gitlab-access AuthorizationPolicy with a port-scoped rule for the same traffic (no source.namespaces rule can match external, non-mesh peers). - CoreDNS rewrites for pg-gitlab.ha.huskypup.net / pg-praefect.ha.huskypup.net so home's own pods reach the floating hostname locally instead of round-tripping through the WAN forward (no NAT hairpin support). Still needed before Phase 1b/1c: UniFi WAN port-forwards for external ports 61442/61443 -> talos-cp-01:32442/32443, source-restricted to the VPS + witness public IPs (manual, same as the existing 61432 rule).

# Brings kube-system/coredns's Corefile under GitOps management. It was

# previously only ever edited live via kubectl (3 existing rewrite rules
|
|
# for auth/rancher/netbird.kube.huskypup.net, none of them git-tracked
|
|
# anywhere in this repo) - every future change meant a manual,
|
|
# classifier-gated live edit to a cluster-wide DNS config instead of a
|

# normal git commit ArgoCD applies on its own. No Talos/kubeadm

# ownerReferences on this ConfigMap or the coredns Deployment (confirmed
