Fornax: COORDINATOR_URL env, port-lease webhook, Grafana dashboard
- Worker deployment: add COORDINATOR_URL and WORKER_ID env vars to portforward-helper; webhook calls coordinator /api/v2/workers/:id/port-lease after each NAT-PMP renewal so coordinator tracks current forwarded port - Worker overlays: patch WORKER_ID env var to actual worker ID (tx253/tx34) - Grafana: fornax-grafana Argo CD app pointing to k8s/fornax/grafana/ ConfigMap with grafana_dashboard=1 label for auto-discovery by sidecar; 7 panels covering bandwidth, active torrents, worker health, request rate, and error rate
