- addMigrations(MIGRATION_1_2) in DatabaseModule eingetragen
- Migrations.kt: Migration(1,2) mit Tabellen-Neubau fuer SQLite < 3.25
  (kcal_per_100g -> kcal_per_kg, min_stock entfernt)
- exportSchema = true + KSP-Argument room.schemaLocation = app/schemas/
- 2.json Schema-Snapshot eingecheckt (Basis fuer kuenftige Migrationen)
- androidTest-Assets zeigen auf app/schemas/ (fuer MigrationTestHelper)
- KrisenvorratDatabaseMigrationTest: 4 instrumentierte Tests
  - Datenerhalt nach Migration
  - Korrekte Spalten nach Migration
  - Indices nach Migration
