Subject: [PATCH] fix: Ausgeblendete Kalender sofort aus Event-Cache entfernen
 Beim Ausblenden eines Kalenders (sidebar_hidden) wurde fetchAndRender() ohne
 force=true aufgerufen, wodurch der Cache nie invalidiert wurde und die Events
 weiterhin angezeigt wurden. Jetzt wird der Cache sofort gefiltert (wie beim
 Checkbox-Deaktivieren), ohne einen neuen Netzwerkaufruf.
