ddadmin 5270273d8a feat(monitoring): add Grafana alert rules and fix datasource binding 
- Why:
  - dashboard panels could resolve to stale datasource uid and show No data
  - monitoring required proactive alerts for ClickHouse health signals

  - fix PromQL metrics for CPU, inserted rows, and parts panels
  - add provisioning alert rules for failed queries, memory resident, and active parts
  - pin Prometheus datasource uid and update monitoring documentation
- Check:
  - POST /api/admin/provisioning/datasources/reload
  - POST /api/admin/provisioning/dashboards/reload
  - POST /api/admin/provisioning/alerting/reload
  - GET /api/v1/provisioning/alert-rules
