A role with users:update could reset an administrator's password or MFA,
change the admin's email to one it controls, or give a colluding account
the ADMIN role (with users:assign-role) - and so become administrator.
Every management action (update, deactivate, activate, reset password,
reset MFA) and every role assignment now requires the target role's grants
to be a subset of the caller's own, like role editing already did. The
target role is read from its grants, so a deactivated admin still counts
as an admin. Changing another user's email revokes their sessions.
