WaitForCOSSucceeded so cleanupSecrets is not called when an existing
ClusterObjectSet remains active after readiness failure. Use create-only
collision handling, or track whether this invocation created the
ClusterObjectSet and delete only that object before deleting its Secrets; add

any is missing. Update the malformed-backup test cases to include an empty

- Around line 382-383: Update CreateClusterObjectSet and its rollback flow so
Secret cleanup uses shared rollback state rather than only the local
createdSecrets list. Ensure cleanup runs after the ClusterObjectSet deletion
succeeds or returns NotFound, including when deletion initially fails with
another error, so RecoverBeforeCE can remove reference Secrets while restoring
the Subscription.

Summary
This PR extends migration test coverage for unsafe, invalid, and failure-boundary cases. It confirms that migration rejects inputs it must not convert and preserves recoverability when conversion or rollback cannot safely finish.
Fixture E2E rejection coverage
The controller-free fixture suite now verifies that conversion is non-mutating when:
UpgradeAvailable).ClusterCatalog.For both cases, the test checks the CLI report/error and asserts that neither a
ClusterExtensionnor aClusterObjectSetis created. It restores the fixture input before the existing successful migration scenario proceeds.Unit coverage and failure safety
check,convert,cleanup, androllback, including missing targets and invalid--allcombinations.ClusterCatalog.Validation
make migration/test-unitmigration/test-e2e-fixture-matrixand run before the successful fixture migration scenario.Scope
This PR intentionally focuses on rejection and recovery behavior. It does not change normal successful migration semantics.
