## Changelog

### Added
- Persist timeseries_workflow.external_id_prefix on DataQualitySettings so runtime and the dashboard can discover custom timeseries workflow IDs.

### Fixed
- data_product_sync no longer looks up timeseries workflows with the instance prefix when a separate timeseries_workflow prefix is configured.
