feat(postgres): add cnpg cluster helmfile and bump operator to 0.29.0 - #161

Conversation
The CloudNativePG operator was deployed declaratively, but the Cluster CR itself was only documented as a manual `kubectl apply` heredoc in the database README. Add database/postgres-cluster.yaml.gotmpl, using the official cnpg/cluster chart (0.8.1) from the repository the operator already comes from, so no new `repositories` entry is needed and the existing Renovate customManager picks the version up. Defaults are lab-shaped and fully parameterized: single instance, no PDB, no superuser access, backups and monitoring off, PostgreSQL 17. Leaving appSecretName empty lets cnpg generate the <clusterName>-app secret. Also bump the operator chart 0.24.0 -> 0.29.0 (app 1.26.0 -> 1.30.0), which had drifted five minor versions behind upstream. Verified on a test cluster: the operator upgrade rolls in place with the existing cluster returning to a healthy state, and a fresh deploy of the cluster helmfile against 1.30.0 comes up healthy on PostgreSQL 17.11 with the app database and owner created.

The operator was deployed declaratively, but the
ClusterCR was only documented as a manualkubectl applyheredoc. This closes that gap.The
cnpg/clusterchart lives in the repository the operator already comes from, so no newrepositoriesentry is needed and the existing RenovatecustomManagerpicks the version up. The operator itself had drifted five minor versions behind upstream.Defaults
Lab-shaped and fully parameterized:
instances: 1,enablePDB: false,enableSuperuserAccess: false, backups and monitoring off, PostgreSQL 17. LeavingappSecretNameempty lets cnpg generate the<clusterName>-appsecret; set it to point at a pre-created basic-auth secret instead.Testing
