fix: address review findings on webhook scaffold

- Comment out manager_webhook_patch.yaml and ../webhook in
  config/default/kustomization.yaml — cert-manager not wired, enabling
  these caused missing Secret volume → controller-manager pod crash
- Comment out webhook_in_openstackcreds.yaml and kustomizeconfig in
  config/crd/kustomization.yaml — conversion webhook strategy set on CRD
  but no /convert handler exists; only a validating webhook is registered
- Add unit tests to openstackcreds_webhook_test.go covering type-assertion
  logic: correct type → (nil, nil), wrong type → non-nil error
- Regenerate deploy/ manifests with webhook resources removed
