Add SiteReplicationActor (runs on every site node) to replicate deployed configs and store-and-forward buffer operations to the standby peer via cluster member discovery and fire-and-forget Tell. Wire ReplicationService handler and pass replication actor to DeploymentManagerActor singleton. Fix 5 pre-existing ConfigurationDatabase test failures: RowVersion NOT NULL on SQLite, stale migration name assertion, and seed data count mismatch.
