Cancel an in-progress failure callback for a failed workflow.

When you retry a failed failure callback using the POST endpoint, it enters an in-progress state.
This endpoint allows you to cancel that in-progress callback before it completes.

The callback must be in an in-progress state. If there's no in-progress callback,
the request will fail with a 400 error.

## Path parameters

- `dlqId` string, required

## Other responses

- `302`: Failure callback canceled successfully
- `400`: Bad Request - No in-progress failure callback to cancel, or callback information is invalid
- `401`: Unauthorized
- `404`: Failure callback not found or message not found
- `500`: Internal Server Error
