Heartbeat detection for contract orders: When the user-set `timeout` time is reached, if neither the existing countdown is canceled nor a new countdown is set, the relevant contract orders will be automatically canceled. This API can be called repeatedly to or cancel the countdown. Usage example: Repeatedly call this API at 30-second intervals, setting the `timeout` to 30 (seconds) each time. If this API is not called again within 30 seconds, all open orders on your specified `market` will be automatically canceled. If the `timeout` is set to 0 within 30 seconds, the countdown timer will terminate, and the automatic order cancellation function will be disabled.
