Link portal triggers through child pipeline results

[yoshifuminakamura]

Summary

Carry Portal trigger metadata through GitLab child pipelines and use it to link results back to trigger runs.

Details

• Forward the parent pipeline ID into generated child pipeline YAML as PARENT_PIPELINE_ID.
• Write parent_pipeline_id into result JSON alongside the child pipeline_id.
• Send manual Portal trigger metadata as BK_TRIGGER_ID, BK_TRIGGER_TYPE=manual_button, and BK_TRIGGER_REASON.
• Resolve Run Cause from direct result metadata, child pipeline IDs, or parent pipeline IDs.
• Show parent pipeline information in the results table and result detail view.
