fix(systems): the bootstrap ask reads the catalog, so its test must supply one (#3027)

CI caught the seam the promotion opened: the standard names now come from an
async catalog read, and the unit test patches systems_svc wholesale — so the
read raised, the fail-open swallowed it, and the ask shipped without the names
it is supposed to carry.

Stub standard_systems in that test, and assert the wiring rather than the
vocabulary: THAT the seeded set is these eight is migration 0087's business and
belongs in the inception integration test, against a real database.

Adds the case the promotion actually created — an unreachable or empty catalog
must still produce the ask. The names are an aid to the question, not the
question; degrading to a weaker nudge is fine, going silent is not.
