Add Fly.io proxy as a third Alloy deployment, document the new
remote_write source in Prometheus, new log source in Loki, and
two new dashboards in Grafana.

Alloy's stage.metrics prefixes all metric names with
loki_process_custom_. Add a relabel rule to strip the prefix so
dashboards can query clean names (flyio_nginx_http_requests_total
etc). Also drop component_id/component_path/filename labels.

Alloy has no built-in prometheus.exporter.nginx component. Remove
the stub_status scraping and connection panels from the Fly.io
dashboard. Replace with error rate and cache hit ratio stats.
All key signals are still covered by log-derived metrics.

The grafana/alloy image is Ubuntu-based (glibc), but our container
uses nginx:alpine (musl). The binary exists but fails with "not found"
because the glibc dynamic linker is missing. libc6-compat provides
the compatibility shim.

The new ACL grant lets the Fly.io proxy reach all Caddy-proxied
services, not just Loki/Prometheus. Document the expanded attack
surface and trust boundary (requires RCE on gilbert or 1Password
access) in both the flyio-proxy and caddy reference cards.

Switch Alloy endpoints from *.tail8d86e.ts.net (with insecure_skip_verify)
to *.ops.eblu.me via Caddy reverse proxy with valid TLS certificates.
Add tag:homelab:443 to flyio-proxy ACL grant so the proxy can reach Caddy.

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).
