+/// Broadcasts Docker container information to the monitoring server for service discovery.
+///
+/// This function sends the current Docker container configuration to the server
+/// to register available containers and enable service monitoring. It will
+/// continuously retry until successful, making it suitable for initial
+/// registration scenarios.
+///
+/// # Arguments
+///
+/// * `base_url` - The base URL of the monitoring server API (e.g., "https://monitoring.example.com")
+/// * `server_id` - The ID of the server to associate the containers with
+/// * `container_dto` - Mutable reference to Docker container information for broadcast
+///
+/// # Returns
+///
+/// * `Ok(())` - When container information is successfully broadcasted to the server
+/// * `Err(Box<dyn Error + Send + Sync>)` - If an unrecoverable error occurs (though the function typically retries on transient failures)
+///
+/// # Behavior
+///
+/// This function operates in a retry loop with the following characteristics:
+///
+/// - **Retry Logic**: Attempts broadcast every 10 seconds until successful
+/// - **Mutation**: Modifies the `container_dto` to set the `server_id` before sending
+/// - **TLS**: Accepts invalid TLS certificates for development environments
+/// - **Logging**: Provides detailed console output about broadcast attempts and results
+///
+/// # Errors
+///
+/// This function may return an error in the following cases:
+///
+/// * **HTTP Client Creation**: Failed to create HTTP client with TLS configuration
+/// * **Network Issues**: Persistent connection failures to the backend server
+/// * **Server Errors**: Backend returns non-success HTTP status codes repeatedly
+/// * **JSON Serialization**: Cannot serialize container data (should be rare with proper DTOs)
