Enhance ContinueWatchingSection with background refresh and loading state management

This update improves the ContinueWatchingSection component by implementing a background refresh mechanism and managing loading states more effectively. The loadContinueWatching function now prevents concurrent refreshes and allows for manual refreshes with a loading indicator. Additionally, the debounce time for background refreshes has been slightly increased, enhancing performance and user experience.
