Pipeline schedule description not displayed on pipelines page

Summary

Pipeline schedule descriptions are not being displayed on the pipelines page (Build > Pipelines), despite the feature being implemented in !169500 (merged). Instead, users see the commit title as a fallback.

This may be the result of changes recently deployed in:

• Change pipeline identifier priority to pipeline name over schedule description

Steps to reproduce

1. Create a pipeline schedule with a description (e.g., "Nightly Security Scan")
2. Run the scheduled pipeline
3. Navigate to Build > Pipelines page
4. Observe the pipeline entry

What is the current bug behavior?

The pipelines page displays the last commit message instead of the scheduled pipeline description.

What is the expected correct behavior?

The pipelines page should display the scheduled pipelines description.
