observability: scrape CloudNativePG postgres metrics (follow-up to #239) (#242)

Follow-up to #239. Every CNPG instance pod already exposes Prometheus metrics on `:9187` (`metrics` port), but nothing scraped them. Adds a single namespace-wide `VMPodScrape` (`namespaceSelector.any`, `selector cnpg.io/podRole=instance`) so the observability VMAgent collects postgres metrics for **all ~23 CNPG clusters** across the estate (authentik, grafana, woodpecker, artifactapi, puppet, litellm, …). No chart changes. Pairs well with the CNPG grafana.com dashboard (20417) as a further follow-up.
