Deploy Fly.io Proxy / deploy (push) Successful in 1m8s
Restrict flyio-proxy ACLs to dedicated tag:flyio-target endpoints (#126)
## Summary
- Introduce `tag:flyio-target` so services must explicitly opt in to be reachable by the fly.io proxy
- Replace broad `tag:k8s` and `tag:homelab` grants with the new tag in the ACL rule and test
- Add `tailscale.com/tags: "tag:k8s,tag:flyio-target"` annotation to docs, loki, and prometheus Ingresses
- Switch Alloy push endpoints from `*.ops.eblu.me` (Caddy) to `*.tail8d86e.ts.net` (Tailscale Ingress)
- Update docs: flyio-proxy, caddy, tailscale, forgejo (future public access + security checklist), expose-service-publicly

## Manual step (not in PR)
Update the k8s operator OAuth client in the Tailscale admin console to include `tag:flyio-target` in its scope. Without this, the operator cannot assign the new tag to Ingress proxy nodes.

## Deployment order
1. **Pulumi ACLs** — `mise run tailnet-preview && mise run tailnet-up`
2. **OAuth client** — Manual update in Tailscale admin console
3. **K8s Ingresses** — `argocd app sync apps && argocd app sync docs loki prometheus`
4. **Fly.io proxy** — `mise run fly-deploy`
5. **Verify** — `mise run services-check`, check Grafana dashboards

## Test plan
- [ ] `mise run tailnet-preview` shows clean diff
- [ ] `argocd app diff docs`, `argocd app diff loki`, `argocd app diff prometheus` show only annotation additions
- [ ] After deploy: Grafana dashboards show continued log/metric flow
- [ ] `curl -sf https://docs.eblu.me` returns 200
- [ ] `mise run services-check` passes
