fix(users): Disable sorting on Permission flag columns

Mark `can_view`, `can_add`, `can_change`, and `can_delete` columns in
the Permissions list as `orderable=False`. Sorting by these computed
flags persisted an invalid sort key which triggers a `FieldError` when
loading `/users/permissions/`.

Fixes #20655
