Grafana tab:
- Datasources table (Name, Type, URL, Default)
- Open Grafana button (opens browser)
- Switch to AlertManager endpoint for real-time active alerts

Prometheus tab:
- Quick query buttons (up, CPU, Memory)
- Metrics browser popup with filter (loads all metric names)
- Rules section (recording + alerting rules Treeview)

CLI:
- --grafana-datasources ALIAS
- --prom-rules ALIAS
