Add batch_id support to pipeline runs

[Mbeaulne]

Description

Added batch ID tracking to pipeline runs by introducing a batch_id field to the PipelineRun interface and related service functions. The createBatchPipelineRuns response now includes a batch_id, which is passed through to savePipelineRun and stored with each pipeline run in the batch.

Checklist

Screenshots (if applicable)

Test Instructions

1. Create a batch pipeline run and verify that the batch_id is properly returned from the API
2. Confirm that individual pipeline runs within the batch are saved with the correct batch_id
3. Verify that existing pipeline runs without batch_id continue to work as expected

Additional Comments

The batch_id field is optional to maintain backward compatibility with existing pipeline runs that were created before batch tracking was implemented.
