Refactor: Try a different approach to fix loading

Attempt to address the persistent loading issue by centralizing authentication and optimizing data fetching.
- Centralized authentication logic in `useOptimizedAuth`.
- Replaced `useAuth` calls in `Index.tsx`, `Dashboard.tsx`, and `useGlobalStats.ts`.
- Further optimizations to data fetching.
