Networking: the superadmin console now mirrors `app` instead of a
loopback-only host port. Base compose drops the host port; the dev
override binds 127.0.0.1:8091; the prod overlay joins the `intranet`
network and listens on :80 with --proxy-headers so NPM can proxy it.
CLI: add `purge-test-users` (dry-run by default, --commit to delete,
--keep allow-list defaulting to the real accounts). Deletes child rows
explicitly (DB-agnostic) plus email-keyed OTPs, so smoke-test signups
that were pointed at prod can be cleaned repeatably instead of via
ad-hoc SQL. Covered by 6 new tests.
