feat: Implement setup screen and login logic

- Add SetupScreen with UI for server URL, username, and password input. - Make SetupScreen the initial screen in the navigation graph. - Implement secure credential storage using EncryptedSharedPreferences. - Create CredentialsRepository and AuthRepository to manage credentials and auth tokens. - Add LoginUseCase to handle the business logic for logging in. - Implement a temporary Retrofit client in ItemRepository to handle login against a user-provided URL. - Integrate login logic into SetupViewModel. - Update all relevant project documentation and DI modules.
