Instrument the flyio-proxy container with Grafana Alloy to collect nginx JSON access logs (→ Loki) and derive request/latency/cache metrics (→ Prometheus). Adds stub_status for connection-level metrics. Includes two Grafana dashboards: Docs APM (per-service) and Fly.io Proxy Health (aggregate). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
