fix: Prevent "Loading Settings" for unauthenticated users

Modified `lib/app/bloc/app_bloc.dart` to correctly initialize the `AppBloc`'s lifecycle status based on the presence of an initial user. This prevents the "Loading Settings" screen from appearing for unauthenticated users before they are directed to the authentication page, ensuring a more accurate and intuitive startup flow.
