Complete GitOps infrastructure setup

Added to kustomization.yaml:
- namespaces.yaml: Centralized namespace management
- auth/: Keycloak authentication system
- keycloak-config.yaml: Identity provider configuration
- sealed-secrets.yaml: Secret encryption system

Fixed namespace conflicts:
- Removed duplicate pomerium-namespace from pomerium.yaml
- Removed duplicate external-dns-namespace from external-dns.yaml
- All namespaces now managed centrally via namespaces.yaml

Now managing 72 Kubernetes resources via GitOps:
✅ Infrastructure: Crossplane providers, external-dns
✅ Certificates: cert-manager, Let's Encrypt, Gandi webhook
✅ Authentication: Keycloak, RBAC configs
✅ Applications: Forgejo, Pomerium, Vaultwarden
✅ Security: Sealed secrets, proper RBAC
