fix: increase minio PVC to 2Ti to match UAT (#1196)

## Summary
- UAT cluster already has a 2TB `minio-data` PVC, but the base manifest
specifies `500Gi`
- Kubernetes rejects shrinking a PVC, causing `oc apply` to fail with:
`spec.resources.requests.storage: Forbidden: field can not be less than
previous value`
- Adds a production overlay patch to set `minio-data` PVC to `2Ti`

Fixes

## Test plan
- [ ] Verify `kustomize build components/manifests/overlays/production`
renders `minio-data` PVC with `storage: 2Ti`
- [ ] Deploy to UAT succeeds without PVC error
