Improve authentication state management and user session handling

Refactors the `AuthProviderComponent` in `useAuth.tsx` to enhance the handling of Supabase authentication state changes. Updates console logs for better debugging, prioritizes setting pending email state before early returns, and refines the logic for `SIGNED_IN`, `INITIAL_SESSION`, and `SIGNED_OUT` events. Also defers Novu updates and profile fetches to prevent blocking the authentication process.
