Covers anonymous → 404, non-admin → 404, and the full admin flow
(list, detail, status change, journal) through a real login and a
real running app. tests/users.test.sqlite is committed and shared by
the whole Selenium session, so the test cleanup also resets the
sqlite_sequence high-water marks that plain DELETEs don't roll back,
keeping the file byte-stable across runs. This run additionally bakes
in migration 0006_create_admin_actions (new admin_actions table), the
first time any Selenium test has booted the real app since that
migration was added — the same one-time process by which migrations
0001-0005 already ended up committed in this fixture.
