Fix WebSocket server startup by using sequential start with port confirmation

- Start 6 server combinations sequentially instead of simultaneously
- Wait for each server port to be listening before starting the next one
- 30-second timeout per server with detailed error logging
- Clear progress reporting for each server startup
- Prevents race conditions and dependency installation conflicts
- More reliable server startup in CI environment
