We will show an overall status of the DataStores in the Dashboard, so there
is no need for a seperate DataStores Status.
This means we can move the Config to where the Status was, and remove
the duplicated entry in the NavigationTree, reducing confusion for users
We can still seperate the permissions by simply showing a permission
denied error, or simply leaving the list empty
