test(cli): the absent-database audit pin counts every audited table, the decision-audit trail included (#21207)

#21432 (#21391) pinned that a dry run of audit-metadata-bodies on an absent
database exits 1 and counts every table it audits as unread. It was
written while the audit read two tables. This branch widens the audit to
the decision-audit trail, so the merged tree reads three. Both intents
are stacked: failures equals the whole audited set, byObject names
exactly those tables, scanned stays 0, exit 1. The set is stated
literally, so a later widening turns the case red rather than passing on
a stale count.
