The module exists in vnctalk/ but is not listed in modules_enabled in
the config template. The test previously passed on external deployments
by coincidence — the test users already had vCards with FN from real
usage. On the compose harness with a fresh DB, the test fails because
nothing generates a vCard.
Add @pytest.mark.skip with a reason pointing to the missing module.
Simplify run-tests.sh to a single pytest invocation (was 12 separate
calls). Update m1-manual-tasks.md §3.5 to reflect the skip.
