Resolve the TODO at support/controlplane-component/controlplane-component_test.go line 74: "TODO(alberto): add StatefulSet test case."

Why

The reconcile logic in the controlplane-component package handles both Deployment and StatefulSet workloads, but the test table only covers the Deployment case. This leaves the StatefulSet path untested and risks regressions.

Acceptance Criteria

• Add a second table entry in the test covering StatefulSet workloads
• Ensure the test validates that reconcile logic handles StatefulSet controllers correctly
• Remove the TODO comment from the source

Technical Details

• File: support/controlplane-component/controlplane-component_test.go line 74
• TODO text: "TODO(alberto): add StatefulSet test case."
• Context: Table-driven reconcile test that currently only has a Deployment entry
