Architektur-Analyse und Korrektur-Konzept

- Umfassende Analyse der aktuellen Implementierung durchgeführt
- Identifiziert: Zwei getrennte User-Systeme (users vs gateway_users)
- Problem: API verwendet falsche Tabelle (users statt gateway_users)
- Lösung: Kompletter Implementierungsplan für korrekte Architektur
- Dokument: ARCHITEKTUR.md mit 6-Tage-Umsetzungsplan erstellt
- Enthält: Custom API-Key Guard, Gateway-User-Credentials, Budget-System
- Swagger/Scramble Paket hinzugefügt (für spätere API-Dokumentation)

Status: Bereit für Implementierung (Start: Tag 1 - Datenbank & Models)
