Behebe SQLite-Bindungsprobleme für produktiven Einsatz

- Verbessere SQLite-Konfiguration mit optimalen Performance-Einstellungen
- Erweitere Dockerfile mit umfassenden Abhängigkeiten für zuverlässige SQLite-Kompilierung
- Füge native Buildflag-Optionen und Umgebungsvariablen für ARM-Kompatibilität hinzu
- Optimiere Startup-Skript mit zuverlässigerer Datenbank-Initialisierung
- Setze korrekte Berechtigungen für Datenbank-Verzeichnis und -Dateien
- Entferne fehlerträchtige Mock-Implementierung zugunsten einer robusten Produktiv-Lösung
