fix: Consistent main menu structure We now have a consisten main menu structure. There are always all entries available. In case the user is in the "sysadmin context" and selects a point regarding the map, he is routed back to "/" and the according component is shown. Otherwise the reselection of an entry acts as before (toggling the visibility of said component).
