Wenn aktiviert, bekommt der JWT-Token statt der üblichen 7 Tage eine Lebensdauer von 180 Tagen. Der Token liegt wie bisher in localStorage, bleibt also bis zum manuellen Löschen / Cookie-Reset gültig. - backend/routers/auth_router.py: LoginRequest.remember_me, längere expires_delta beim Token-Erstellen - index.html: Checkbox unter dem 2FA-Feld - api.js: login() reicht remember_me als 4. Parameter durch - app.js: Wert aus #login-remember lesen und mitschicken - Version v5 → v6
