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 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.

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).

## Summary
- Adds a Fly.io reverse proxy (`blumeops-proxy`) that tunnels public traffic to homelab services over Tailscale
- First service exposed: `docs.eblu.me` — the Quartz static docs site
- Includes Pulumi IaC for Tailscale auth key/ACLs and Gandi DNS CNAME
- Adds mise tasks (`fly-deploy`, `fly-setup`, `fly-shutoff`) and Forgejo CI workflow
## Key details
- Fly.io Firecracker VMs support TUN devices natively — no userspace networking needed
- Tailscale auth key is `preauthorized=True` to avoid device approval hangs on container restarts
- nginx caches aggressively for the static site; health check is on the default_server block
- ACLs restrict `tag:flyio-proxy` to `tag:k8s` on port 443 only
- DNS CNAME deployed and verified: `docs.eblu.me` → `blumeops-proxy.fly.dev`
## Test plan
- [x] `curl -sf https://blumeops-proxy.fly.dev/healthz` returns `ok`
- [x] `curl -I -H "Host: docs.eblu.me" https://blumeops-proxy.fly.dev/` returns 200 with `X-Cache-Status`
- [x] `curl -I https://docs.eblu.me/` returns 200 with valid Let's Encrypt cert
- [x] `dig forge.ops.eblu.me` still resolves to 100.98.163.89 (private services unaffected)
- [x] Set `FLY_DEPLOY_TOKEN` Forgejo Actions secret for CI auto-deploy
