C2(deploy-infra-alerting): impl add textfile staleness and Frigate alerts

- TextfileStale: fires when a .prom textfile on indri hasn't been
  updated in 1 hour (node_textfile_mtime_seconds). Covers borgmatic,
  zot, minikube, jellyfin exporters.
- FrigateCameraDown: fires when frigate_camera_fps drops to 0 for 5m.
- Add runbooks for both alerts.
