Support WorkerRun on TranscriptionEntity
- add
worker_run_idFK onTranscriptionEntity(nullable, blank) - make it available in the admin details of an TranscriptionEntity, using
raw_id_field - expose it in
CreateTranscriptionEntityendpoint
Rules for endpoints:
- we only support
worker_version_idXORworker_run_id, raise a 400 if both are supplied - the endpoint must load the
WorkerRunfrom its ID to check its existence - and use the related
WorkerVersionasworker_version_idon the resulting transcription-entities (so we end up with both worker_version & worker_run being set on the TranscriptionEntity)
