Offline detection is now more deeply integrated

Changes

Added setupListeners to store.ts in order to make fetched data be refetched automatically when the user's internet connection is restored
Added the same refetching code that is used for the other api files to notificationApi
Refactored out the internet connection code in NetworkDetector into its own hook
Refactored out the infinite loading functionality in useLiveNotifications into its own hook and made it generic. The original useInfiniteLoading hook has been replaced by this hook.

Multiple duplicate key warnings will be shown for the unread notifications view if the user reconnects and they received notifications while they were offline. However, the user won't experience any issues since the clear method inside of the useInfiniteLoading hook will eventually be called.
I found that the resetApiState() call was only necessary for the notification functionality. So, that's why the useInfiniteLoading hook has an optional resetApiStateFunction argument.
