Implement Queue for Data Transmission to Broker During Connection Interruptions

When the broker connection is unavailable at the time of transmission, results from data requests and status updates cannot be sent, resulting in data loss or workflow interruptions. To address this, we propose creating a queue to store transmissions when the broker is unreachable. The system will attempt to send queued data once the connection is reestablished. Additionally, introduce a new status, such as "Preparing to Send," to indicate that data is queued for transmission.
