Koha::Biblio::Metadata->store() now repairs recoverable MARCXML faults
before saving, so this test's invalid data no longer reaches the DB
and detail.pl never hits a decoding error.
Write the metadata directly via the DBIC row instead, bypassing
store()'s repair, so the test still exercises detail.pl's own
defensive handling of corrupt metadata.
Test plan:
prove t/db_dependent/selenium/regressions.t
