fix(marketing): call marketing.landing view directly (avoid redirect loop)

recordings.index previously redirected anonymous users to
url_for('marketing.landing'), but both endpoints are mounted at '/'.
Since recordings_bp registers first, Flask's URL map routed back to
recordings.index -> infinite redirect loop. Now we invoke the marketing
landing view function directly for anonymous requests, preserving the
URL map and avoiding the loop.
