Tomas DvorakandDevin f2aa9ceba8 feat(infra): external monitoring stack (Beszel + Prometheus/Grafana)
Homelab monitoring design (docs/specs/2026-10-03-external-monitoring.md):
Beszel agents own the two physical hosts, prometheus-pve-exporter covers
every LXC/VM via the PVE API with no guest agents, and Grafana supplies
graphs. Dash needs zero code changes — JSON-path widgets already carry an
Authorization header and can walk Prometheus/Beszel JSON, embed widgets
iframe Grafana panels, and monitors + notification transports provide
the alerting layer for unmanaged hardware like the CM834 switch.

infra/monitoring/ ships compose.yaml, prometheus.yml, pve.yml.example
(gitignored real file), and Grafana datasource provisioning.
docs/monitoring.md documents deployment and widget recipes.
