feat(pwa): implement service worker and PWA enhancements

- Added service worker (sw.js) for offline functionality, caching strategies, and performance improvements.
- Registered service worker in App component to manage updates and offline readiness.
- Introduced ServiceWorkerStatus component to display connection status and provide cache management controls.
- Created manifest.json for PWA configuration, including app name, icons, and display settings.
- Updated index.html with PWA meta tags and links to support mobile web app capabilities.
- Refactored authentication guards to utilize useAuthStatus hook for improved user state management.
- Removed deprecated unregister-sw.js file to streamline service worker management.
