Add comprehensive debug logging for screenshot rendering

Browse Source 
- Timer callback: log each tick and commit status
- LockedSurface::update(): log background presence, fade alpha, feedback states
- Renderer::render(): log background drawing and fade alpha
- Ready event: log background set confirmation

These logs will help diagnose why screenshots are not displaying.
