/*
    Critical path: user management and permission control.

    As administrator: create a limited permission group, create a user in
    it, then prove from a second browser context that the restricted user
    can sign in, sees only permitted modules and is refused by admin-only
    endpoints. Finally remove the user and the group and prove both are
    really gone (including that the removed user can no longer sign in).
