Currently, the assisted installer installation manifests require certain resources to remain undeleted while the assisted installer components perform their cleanup operations. Specifically, the BareMetalHost resource depends on both the InfraEnv and the Namespace remaining in a non-terminated state to complete its cleanup successfully.

To address this, the ClusterInstance deletion process needs to be enhanced to wait for all manifests in a sync-wave group to be deleted before progressing to the next group.

Additionally, the default assisted installer templates may require regrouping of installation manifests to ensure proper sequencing and support for BareMetalHost cleanup operations.

Acceptance Criteria:

1. The ClusterInstance deletion logic processes sync-wave groups sequentially, ensuring dependencies are respected.
2. Default Assisted Installer templates are reviewed and updated if required to support proper cleanup of resources.
3. Verify that BareMetalHost cleanup completes successfully without premature termination of required resources.

Notes:

• This change ensures compatibility with the assisted installer cleanup requirements and avoids failures during the deletion process.
