peter 24c93cbb83 docs: name the Configuration tab as it is rendered, drop an unused fixture
Round 6's two remaining nits. The operator note said "Configuration → Email"
but the group renders as "Email / SMTP" in both locales, and
test_an_admin_can_activate_a_pre_approved_registrant requested make_user without
using it — a leftover from the reverted rounds that made the test look like it
seeded an admin when it did not.

"""Auth / session security core (TEST-1), DB-lane.
The wallet impersonation gate, epoch-based session revocation, single-use tokens and the
enumeration-safe uniform 401 are the security mag, and had zero tests (only `_oauth_redirect_uri` was
covered). Starlette's SessionMiddleware round-trips the signed cookie under TestClient, so the whole
browser-less flow is exercisable. Uses the real auth stack via the `client` fixture (NO current_user
override) so login, the wallet gate and epoch revoke are the code under test.
Note: `/api/me` is the bootstrap probe — it returns 200 `{authenticated: False}` when logged out, not a
401. A revoked session is therefore checked on a PROTECTED endpoint (`/api/feed`), which does 401.
