refactor: extract test data generator to server/test_mode.py

Browse Source 
- TestDataGenerator class: builds 324-byte Forza packets, runs async loop at 30fps
- Simulated data passes through _handle_packet (parser -> WS -> forwarder)
- Listener delegates to test_mode.get_generator()
- Cleaner separation: listener.py no longer contains test logic
