- Backend: beforeId-Parameter + GetActiveMessagesBeforeId + GetActiveMessageCountBeforeId - Frontend: Button 'X ältere Nachrichten laden' statt Info-Text - Archiv-Button erscheint erst wenn alle älteren Nachrichten geladen - Scroll-Position bleibt beim Nachladen erhalten - Fix: wwwroot Quell-Dateien mit publish synchronisiert
