Add JSON schema generation for kubeconform CRD validation

- ci/generate-schemas.sh generates schemas from CRD manifests and K8s swagger
- Sources: ArgoCD v3.3.2, Gateway API v1.5.1, Kubernetes v1.33.7
- Optionally fetches live cluster CRDs via kubectl when available
- Generated schemas committed to schemas/ for CI use
- Run `make schemas` to regenerate after CRD version bumps
- validate-apps.sh and validate-clusters.sh check local schemas first
