Replace Homepage Helm chart with kustomize manifests and custom Dockerfile (#221)
## Summary
- Replace third-party Helm chart (jameswynn/homepage v2.1.0, pinned at app v1.2.0) with plain kustomize manifests and a custom Dockerfile building from forge mirror at v1.10.1
- Adds Dockerfile (`containers/homepage/`) with multi-stage build (node:22-slim builder, node:22-alpine runtime)
- Creates kustomize manifests: Deployment, Service, ConfigMap (6 config files), ServiceAccount, ClusterRole, ClusterRoleBinding
- Keeps existing ingress-tailscale.yaml and all 6 ExternalSecret resources unchanged
- Updates ArgoCD app definition from multi-source Helm to single directory source
## Prerequisite
- Homepage source mirrored at forge.ops.eblu.me/eblume/homepage.git ✅
- Container must be built and pushed before syncing: `mise run container-release homepage v1.10.1`
## Deployment and Testing
- [ ] Build and push container image: `mise run container-release homepage v1.10.1`
- [ ] Branch-test via ArgoCD: `argocd app set homepage --revision feature/homepage-kustomize && argocd app sync homepage`
- [ ] Verify dashboard loads at go.ops.eblu.me / go.tail8d86e.ts.net
- [ ] Verify k8s autodiscovery works (services appear on dashboard)
- [ ] Verify widgets load (weather, Forgejo, Jellyfin, etc.)
- [ ] After merge: `argocd app set homepage --revision main && argocd app sync homepage`
