Under the specific situation where a user has logged into the site and puts their computer to sleep, an error page redirection can happen when they come back to begin working working again. This was due to the fact that the auto renew couldn't work properly due to the login session token and refresh token both being expired by this point. It would be ideal for the behavior to be that it redirects the user to the home page instead.

Changes

• Refactored axios to throw its request and response rejection errors
• Refactored the useSblAuth api to automatically log a user out (and redirect them) if their access and redirect tokens are expired
• Split App.tsx into three component files to improve readability
• Added some commented out placeholder logic to app that can be used for notifying the user of impending idle logout
• Refactored the ProtectedRoute to longer needs the auth object passed to it since it can just pull it in as a hook
