Update LED bar to handle message type field

- Process 't' field to distinguish between beat ('b') and update ('u') messages
- Beat messages: execute pattern immediately using current parameters
- Update messages: only update parameters, don't execute pattern
- Maintains backward compatibility with default to beat if 't' not specified
- Enables proper synchronization between controller and bars
