This commit implements a complete authentication flow, including user registration.
- Introduces an `AuthRegisterRequested` event to handle user registration.
- Persists the user ID in settings upon successful authentication.
- Modifies `AuthBloc` to load the user based on the stored ID, improving app launch persistence.
- Refactors `UserCubit` to only manage the user state and removes authentication logic.
- Removes `UserCubit` initialization from `main.dart` and triggers `AuthStarted` to initiate the authentication process.
