change input/output port name & remove viewmodel dependencies [FoKE-Developers#22]

- AppPreferencesRepository -> AppPreferenceInterface
- AppPreferencesRepositoryImpl -> AppPreferencesRepository
- GetSampleUiData -> GetSampleDataInterface

* 변경 전 참조 구조
   - ViewModel -> GetSampleData -> GetSampleUseCase -> AppPreferenceInterface -> AppPreferencesRepositoryImpl

* 변경 후 참조 구조
   - ViewModel -> GetSampleDataInterface -> GetSampleUseCase -> AppPreferenceInterface -> AppPreferencesRepository
