fix(access): always display readable access level for ACCESS_* constants

Labels for global ACCESS_* constants should always be meaningful,
and not Limited. Most obvious example is when write access arrays
are not populated with ACCESS_PUBLIC in a walled garden mode.
Or else when certain global access levels are filtered by hooks
for a select group of users
