🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Use a wait-only helper for OLMv1 cleanup verification.

ensureCleanupWebhookConfigurations deletes matching webhook configurations before it waits for their removal. If OLMv1 fails to remove a configuration, this DeferCleanup deletes it and then passes, masking the finalizer-cleanup regression. Use a wait-only helper here, or add an option that skips the delete phase while preserving the existing stale-resource cleanup in BeforeEach.

In `@openshift/tests-extension/test/webhooks.go` at line 465, Replace the deferred
cleanup call to ensureCleanupWebhookConfigurations with a wait-only cleanup
verification helper or mode that does not delete webhook configurations, so
failed OLMv1 removal remains detectable; preserve the existing deleting cleanup
behavior in BeforeEach.
