feat(logout): implement cache cleanup and service worker unregistration on logout

- Added a new utility, CacheCleanup, to handle clearing caches and unregistering the service worker during user logout.
- Enhanced the LoggingOutPage to utilize CacheCleanup for clearing local session and caches before redirecting to the login page.
- Introduced ModuleErrorBoundary to manage module loading errors, providing user feedback and options to retry or reload the application.
- Updated App component to include global error handlers for improved error management related to module loading issues.
