feat: create OpenOva monorepo structure
Consolidate all component repos into a single monorepo:
- core/: Bootstrap + Lifecycle Manager application
- platform/: Individual component blueprints organized by category
- networking/ (cilium, k8gb, external-dns, stunner)
- security/ (cert-manager, external-secrets, vault, kyverno, trivy)
- observability/ (grafana stack)
- storage/ (minio, harbor, velero)
- scaling/ (keda, vpa)
- failover/ (failover-controller)
- gitops/ (flux, gitea)
- idp/ (backstage)
- data/ (cnpg, mongodb, valkey, redpanda)
- communication/ (stalwart)
- iac/ (terraform, crossplane)
- identity/ (keycloak)
- meta-platforms/: Bundled vertical solutions
- ai-hub/ (enterprise AI platform)
- open-banking/ (PSD2/FAPI fintech sandbox)
- docs/: Platform documentation (PLATFORM-TECH-STACK.md, SRE.md)
All internal links updated to use relative paths within monorepo.
