Fix sports managers background updates and update intervals (#51)

- Add all sports managers to background updates in display_controller.py
- Add all sports managers to deferred updates when scrolling
- Fix hardcoded update intervals in NHL, NBA, NCAA Basketball, and NCAA Hockey managers
- Use config values for recent_update_interval and upcoming_update_interval
- Ensure all sports managers update continuously in background
- Only NFL managers had the season fetching issue, others were already optimized
