fix: defer steering wheel SDK init until game window exists

LogiSteeringInitialize fails during DLL_PROCESS_ATTACH because
the game window doesn't exist yet. Now tries multiple approaches:
1. InitWithWindow + GetDesktopWindow
2. InitWithWindow + GetForegroundWindow
3. Simple init (no window)
4. Deferred init on first SetLEDs call (game window guaranteed)
