root 2d874d3969 fix: two observability bugs from initial deployment
buildbot/nix-eval Build done. (1 warning)
Details
buildbot/nix-build Build done.
Details 
Fix 1 - UnPoller 404 on UDM Pro:
  Remove :8443 from UP_UNIFI_DEFAULT_URL. UniFi OS devices (UDM Pro,
  UDM, UXG, CloudKey) use a different API path and do NOT use port 8443.
  URL should be https://10.42.1.1 (no port); unpoller handles the
  /proxy/network path internally for UniFi OS devices.

Fix 2 - Grafana dashboards showing invalid datasource:
  Add uid = "prometheus" to the provisioned Prometheus datasource.
  Without an explicit UID, Grafana auto-generates one on first run.
  All dashboard JSON references datasource uid "prometheus" which
  only works if the provisioning explicitly sets that UID.

root df2f9d69fe fix: address PR feedback + expand infrastructure coverage
buildbot/nix-eval Build done. (1 warning)
Details 
- Replace unpoller-credentials plain Secret with ExternalSecret
  pulling from Bitwarden item 15bfc957-5de5-49b2-ab6c-b41800e71564
  via bitwarden-login ClusterSecretStore (username + password)
- Pull UP_UNIFI_DEFAULT_USER from secret as well (was hardcoded)

- Add OpenWRT access point (10.42.0.3) to genesis DNS hosts file
  as ap.thehellings.lan (discovered during network scan)

- Add blackbox exporter to genesis (port 9115, ICMP module)
  for probing non-NixOS infrastructure that has no node_exporter:
  OpenWRT AP, Joel, pve1, chronicles, nas1, odoo, mattermost,
  homeassistant, USW-Pro-HD-24 UniFi switch

- Add infra_ping scrape job to Prometheus using blackbox prober
  targeting all non-NixOS LAN hosts via genesis blackbox exporter

root ab6e1d24fe feat: comprehensive observability stack 
- Add restic_backups and mattermost scrape jobs to Prometheus config
- Add UnPoller deployment+service+secret for UniFi metrics (unpoller.yaml)
- Add unifi scrape job targeting unpoller in-cluster
- Add 4 Grafana dashboards as NixOS-managed etc files on hosea:
  - system-health: CPU, memory, disk, network per host
  - backup-health: restic backup freshness and duration
  - kubernetes: pod counts, restart rates, node resources
  - network: DNS queries, DHCP leases, UniFi ports, ping latency
- Add grafana-api-token agenix secret placeholder on hosea
- Open firewall ports 9100/9427/9558 for prometheus exporters in baseline.nix
