/// Zentraler Appwrite-Client (Session-Cookies werden vom SDK verwaltet).
///
/// **Wenn `database_not_found` trotz angelegter DB:**
/// 1. In der Console **dieselbe Project-ID** wie in der App (Profil → Appwrite).
/// 2. Unter Databases die **Database ID** kopieren (nicht nur den Namen) und in
///    [lib/appwrite_local.dart] bei `kAppwriteDatabaseIdOverride` eintragen.
/// 3. Oder per Build: `--dart-define=APPWRITE_DATABASE_ID=deine_id`
///
/// **Console-Setup (einmalig):**
/// Optional: Collection/Bucket per Skript – im Projektroot `.appwrite_api_key`
/// (eine Zeile = Server-API-Key, siehe `.appwrite_api_key.example`), dann
/// `./tool/run_appwrite_setup.sh` ausführen.
/// 1. **Auth:** E-Mail/Passwort aktivieren.
/// 2. **Plattformen:** Bundle-ID `com.example.handwerksapp` (macOS/iOS/Android)
///    unter Settings → Platforms eintragen (sonst „Invalid Origin“).
/// 3. **Database** mit ID wie in [kAppwriteDatabaseId] (oder Override in
///    `appwrite_local.dart`).
/// 4. **Collection** mit ID wie [kAppwriteCollectionId] — wegen Appwrite-1.8-Limit
///    nur **zwei** String-Attribute: `userId` (required, Index) und `extendedJson`
///    (JSON mit `v: 2`, kompletter Datensatz inkl. Fotos/Unterschrift; siehe
///    [Auftrag.toMap] / [Auftrag.fromAppwriteDoc]).
/// 5. **Storage-Bucket** mit ID [kAppwriteBucketId].
