Deploys kube-prometheus-stack via helm-controller: Prometheus, Grafana (internal-only), node-exporter, kube-state-metrics. Adds prometheus-pve-exporter for Proxmox (token in an out-of-band Secret), scrape configs for external hosts (.48/.70/.71/.49), community dashboards (Node Exporter Full, Proxmox via Prometheus) and a custom Hardware Temperatures dashboard. Grafana liveness made tolerant for slow first-boot migrations.
