KI-Chatfunktion aus TaskMate entfernt

Die ungenutzte Chat- und Assistant-Funktion wurde vollständig ausgebaut. Backend-Route inklusive routes/assistant.js, Frontend-View, Navigationseintraege, Service-Worker-Cache und der PROXY_TOKEN-Verweis sind entfernt. Die Datenbank bleibt unveraendert, die Tabellen assistant_sessions und assistant_messages bleiben als Altdaten bestehen.
