Security fixes

GHSA-fjgc-484v-j6mf - missing permission check on update_user_role API endpoint

Suggested action: update immediately if using scoped admin accounts without AccessRolesAssign permission.

An scoped admin user without the AccessRolesAssign permission was able to re-enable existing expired or revoked access role assignments due to a missing permission check, allowing them to reinstate target access for a user that used to have it in the past.
