#166: Add delivery status indication for messages

This update introduces a new property, `isDelivered`, in the message struct to track if a message has been successfully sent or not. Additionally, this also includes a new helper function `IsDelivered` to easily retrieve the status. This feature enhances the tracking capabilities of outgoing messages across different client files.
