Description of the problem:
If an orchestrator CR that deployed the RHDH operator is deleted, the RHDH operator and backstage instance keep running. The rhdh-operator ns is not terminated.  

How reproducible: 100%

Steps to reproduce:

1. Deploy orchestrator operator 1.5.0-2025-03-11 

2. Deploy orchestrator CR that deploys RHDH

3. After all resources are created, delete the orchestrator CR

Actual results:
Other resources that were deployed by the Orchestrator, like OSL and SL are deleted. The RHDH operator and backstage instances are not removed.

Expected results:
If orchestrator deployed RHDH it should remove it.
