Trigger Sync

Trigger a full sync of requesters from the configured ITSM provider. Uses provider-agnostic ITSMClient implementations (Story 1.7) and upserts into the local requester table using (provider_type, external_id). Note: This is a long-running operation. For production, consider using a background task queue (e.g., Celery, AWS Lambda).
