Erich Blume 3679124ebd Expose Kubernetes API as Tailscale service (Step 0.14) (#27)
## Summary
- Add `tag:k8s-api` to Pulumi ACLs and indri device tags
- Configure Tailscale serve with TCP passthrough for k8s API at `k8s.tail8d86e.ts.net`
- Update minikube role to include `k8s.tail8d86e.ts.net` in certificate SANs
- Add `apiserver_port` config option (internal port 6443, dynamic host port with podman driver)
- Document Step 0.14 in k8s-migration plan (added post-Phase 0 completion)

The Kubernetes API is now accessible at `https://k8s.tail8d86e.ts.net` using TCP passthrough to preserve mTLS authentication.

## Deployment and Testing
- [x] Pulumi ACLs applied
- [x] Tailscale service created and approved in admin console
- [x] Minikube cluster recreated with new cert SANs
- [x] tailscale serve configured with TCP passthrough
- [x] 1Password credentials updated with new certs
- [x] Kubeconfig updated on gilbert
- [x] `mise run indri-services-check` passes
- [x] `kubectl --context=minikube-indri get nodes` works via Tailscale

"""Pulumi program to manage tail8d86e.ts.net tailnet configuration.
This program manages:
- ACL policy (grants, SSH rules, tag owners, tests)
- Device tags for infrastructure classification
Devices are tagged based on their role:
- tag:homelab - Server infrastructure (indri)
- tag:workstation - Development machines that can manage homelab (gilbert)
- tag:nas - Network-attached storage (sifaka)
- tag:blumeops - Resources managed by this IaC
- Service tags (grafana, forge, etc.) - Fine-grained service access control
