[Release fix] Fix reference to temp_pipeline_workflow (#402)
[Release fix] Fix reference to temp_pipeline_workflow (#402)

# Description

- Bug with premature removal of a `temp_pipeline_workflow` reference. The mNGS runs won't have the `WorkflowRun` but still need to read `short-read-mngs` for the frontend.

# Tests

- Verified that the workflow is being passed to the Sample Details sidebar.

- QA: This should fix CH-29466 !
