domain/repository/ImportExportRepository.kt: new interface with
exportToJson() and importFromJson(json) suspend functions.
data/export/ExportData.kt: serializable data class bundling all
entity lists for JSON serialization via kotlinx.serialization.
data/export/ImportExportRepositoryImpl.kt: implementation using
kotlinx.serialization + Dispatchers.IO; exportToJson fetches all
DAOs and serializes, importFromJson deserializes and upserts back.

upsertAll() suspend function to each DAO to support bulk import.
di/RepositoryModule.kt: bound ImportExportRepositoryImpl to
ImportExportRepository via Hilt @Binds.

DAOs for unit test coverage.

- 4 Implementierungsklassen in data/repository/ mit Hilt @Inject
- RepositoryModule mit @Binds-Bindings fuer alle Repositories
- Datumslogik (getExpiringSoon) aus ItemDao in ItemRepositoryImpl verschoben
- 20 Unit-Tests mit Fake-DAOs (4 pro Repository)
- DatabaseModule: @Module + @InstallIn(SingletonComponent) with @Singleton-scoped
Room.databaseBuilder provider and four @Provides methods for ItemDao,
CategoryDao, LocationDao and SettingsDao
- DatabaseModuleTest: smoke-test verifies all four DAO providers return
non-null objects using an in-memory Room database
- KrisenvorratDatabase mit allen 4 Entities und LocalDateConverter
- CategoryDao, LocationDao, ItemDao, SettingsDao mit CRUD und Flow-Queries
- ItemDao.getExpiringSoon(daysUntil) als Default-Interface-Methode
- SettingsDao mit @Upsert (Room 2.6.1)
- Instrumentierungstests für alle 4 DAOs (in-memory DB)
- androidx.room:room-testing zu Dependencies ergänzt
- Add CategoryEntity, LocationEntity, SettingsEntity, ItemEntity
- ItemEntity: FK to Category+Location with CASCADE, indices on FK columns
- LocalDateConverter: LocalDate? <-> String? (ISO-8601) via @TypeConverter

app/build.gradle.kts:
- Enabled buildConfig in buildFeatures to expose VERSION_NAME
app/src/main/java/de/krisenvorrat/app/MainActivity.kt:
- Replaced plain Text greeting with centered Column layout
