[bagusnl]

Main Goal

This is interim commit before @neon-nyan take precedence over at fecc199

1. Move CTSW creator outside while loop to prevent self recreation
2. Always pause carousel when window is not in foreground
3. Properly break the for loop when CTS is called
4. Delay stop scroller to wait for scroller to initialize
5. Pause/resume carousel on tray activity
