Adds externalClusters connectionParameters + replica.self/primary/source to all four Cluster CRs (home pg-gitlab/pg-praefect, VPS pg-gitlab/pg-praefect), turning last commit's recovery-only replicas into real CNPG streaming replicas - exact pattern already proven for pg-authentik. TLS certs copied cross-cluster manually (kubectl, not git, same as every other cross-cluster secret in this plan). Also adds pg-gitlab-app/pg-praefect-app password sync (PushSecret home -> Vault -> ExternalSecret VPS, Merge policy) - CNPG-generated passwords stay in sync via WAL replication but the K8s Secret OBJECTS never resync on their own, same gap already closed for pg-authentik-app. VPS's standalone clusters were already destroyed and recreated as recovery-mode replicas in the prior commit (with the user's explicit help running the classifier-blocked kubectl delete) - this commit turns on the actual streaming replication on top of that.

# Explicit params added 2026-08-22 (GitLab cross-site replication plan)
|
|
# - this cluster ran on bare Postgres defaults before. A VPS replica
|
|
# can't replay WAL past a checkpoint recorded with higher settings than
|
|
# its own ("recovery aborted because of insufficient parameter
|
|
# settings", confirmed live for pg-authentik) - giving both sides an
|
|
# identical explicit block up front means nobody can tune one side
|
|
# later and silently break replication.
