The values_showcase-rbac.yaml has a custom initContainers configuration that overwrites the Helm chart's default. This was done to create RBAC conditional policies, but as a side effect it doesn't set CATALOG_INDEX_IMAGE, which means the catalog index is never used in showcase-rbac tests.

Current state:

• showcase deployment - uses Helm chart default initContainer (no override)
• showcase-rbac deployment - overrides initContainer entirely

Problems:

• Bugs in the catalog index flow only surface in showcase, not in showcase-rbac
• showcase-rbac tests a different code path than what production users would experience
• If Helm chart's default initContainer changes, showcase-rbac won't pick up those changes

Recommendation:
showcase-rbac should not override the initContainer, to be consistent with showcase. The RBAC conditional policies setup should be handled through a different mechanism (e.g., ConfigMap, additional initContainer) instead of overwriting the install-dynamic-plugins initContainer.
