🐛(frontend) fix legacy role computation

Before the subpages feature, the user_role was
computed thanks to the abilities.
This is not the correct way to do it anymore,
the abilities are now different.
We now have "user_role" in the doc response
which is the correct way to get the user role
for the current document.
