Run a bulk job. This is step 3 of the 3-step bulk flow (create job → add users → run). Once triggered, Courier begins sending messages to all ingested users. The job cannot be modified after this call.
Poll GET /bulk/{jobId} to check job status. Individual message statuses are available via the Messages API using each recipient’s message_id.
