test(metadata-protocol): a form member carries no label or name; enumerate a named variant only where the member's schema declares name

The save door refuses `label` and `name` on a form view, so the probes and
the packaged form fixtures carry neither, and the member-kind derivation
offers a named variant only for a slot whose own schema declares `name`.
