Get contact unlock task
Poll an email-unlock task created by the contact email submission endpoint.
Store the returned task_id and use it here to make the workflow resumable across background jobs, frontend refreshes, or retries. Continue polling while taskStatus is pending or processing, then stop when it reaches completed or failed. Use a controlled polling interval and treat each read as a status check, not a new unlock request.
Task completion does not guarantee an email for every submitted person. Process item-level status, email, and error information independently, persist successful results, and do not retry the same task after it reaches a terminal state.
