httpx's cookie jar only auto-attaches Secure cookies to https:// requests.
Switching the ASGITransport client fixture's base_url from http://test to
https://test (no real socket is opened either way) makes it behave like a
browser talking to the Cloudflare-Tunnel-terminated HTTPS edge in
production, eliminating the need for manual client.cookies.set(...)
re-injection workarounds in test_auth.py.

Production code shouldn't branch on `"pytest" in sys.modules` — it's
fragile and couples db.py to test tooling. Instead, conftest.py now
builds its own dedicated NullPool engine directly from settings, used
only for the drop_all/create_all reset and the get_db override. The
production engine in app/db.py is untouched and never exercised during
tests, so this fully preserves the event-loop fix while keeping prod
code test-agnostic.
