Split out of #281 per review: the VerticalPodAutoscaler CRDs land first, together with their generated kubeconform schemas, so CI can validate the VPA objects that follow.
- Adds apps/base/vpa-system with the v1.7.0 VPA CRDs served via the artifactapi github remote (terraform-artifactapi#14, merged)
- Adds schemas/autoscaling.k8s.io/ (verticalpodautoscaler + checkpoint, v1 and v1beta2) generated with the same transform as ci/generate-schemas.sh (from the CRD manifest rather than the live cluster, since the CRDs are not installed yet)
- Wires the vpa-system overlay into the platform applicationset
Verified: kustomize renders both CRDs; a sample updateMode Off VPA passes kubeconform against the new schemas. Merge before #281 (recommender) and #283 (per-workload VPAs).
