Phase 1b: Deploy docs hosting with Quartz (#85)

## Summary
- Add ArgoCD Application and manifests for `quartz` service
- Add `docs.ops.eblu.me` to Caddy reverse proxy configuration
- ConfigMap points to blumeops v1.0.0 release tarball
- Tailscale ingress with homepage annotations for auto-discovery

## Deployment and Testing

**Pre-deployment (container build):**
- [ ] Build and tag quartz container: `mise run container-tag-and-release quartz v1.0.0`

**K8s deployment:**
- [ ] Sync apps: `argocd app sync apps`
- [ ] Point quartz at feature branch: `argocd app set quartz --revision feature/docs-phase-1b-hosting`
- [ ] Sync quartz: `argocd app sync quartz`
- [ ] Verify pod is running: `kubectl --context=minikube-indri get pods -n quartz`
- [ ] Verify Tailscale ingress: `kubectl --context=minikube-indri get ingress -n quartz`

**Caddy deployment:**
- [ ] Dry run: `mise run provision-indri -- --tags caddy --check --diff`
- [ ] Apply: `mise run provision-indri -- --tags caddy`

**Verification:**
- [ ] Test https://docs.tail8d86e.ts.net
- [ ] Test https://docs.ops.eblu.me
- [ ] Verify homepage dashboard shows docs link

**Post-merge:**
- [ ] Reset to main: `argocd app set quartz --revision main && argocd app sync quartz`
