Konfliktauflösung kombiniert beide Seiten: - Auth: Secure-Cookie-Flag + DB-Session-Handler (main) - UniFiController: createVouchers (n-Parameter, 1 API-Call) + QoS-Optionen (main) - index.php: IP-Rate-Limit/PRG/Sticky-Forms + CAPTCHA/SMS/QoS/Tageslimit (main) - users.php: 2FA-Reset (main) auf POST+PRG umgestellt wie übrige Aktionen - forgot_password: Session-Throttle (main) + IP-Throttle kombiniert - Eigene Migrationen wegen Nummernkollision auf 0005/0006 umbenannt https://claude.ai/code/session_01KKVpVPJjrTKGoRgpJcySD4
