Refactor code for better readability and maintainability

- Add method to get token and validate in AuthCubit
- Update AuthState with loading, success, and error states for token
- Use BlocBuilder in SplashView for token validation and navigation

This commit refactors the code in AuthCubit to include a method to get the token and validate it. It also updates the AuthState with loading, success, and error states for token handling. In SplashView, BlocBuilder is now used to handle token validation and navigation based on the token status.
