C2(deploy-infra-alerting): impl add probes and alert rules for services-check coverage
Extend Alloy blackbox probes:
- Add prometheus, loki, grafana, teslamate, immich, navidrome
- Now probing 11 services (was 5), covering most HTTP checks from
services-check
Add alert rules:
- PostgresClusterUnhealthy: cnpg_collector_up < 1 for 3m (critical)
- PodNotReady: kube_pod_status_ready{condition="true"} == 0 for 5m
Add runbooks:
- runbook-postgres-unhealthy.md
- runbook-pod-not-ready.md
