Alerts: make /alerts public, require sign-in to save

Anyone can open /alerts and build an alert (category, term, recency,
frequency). Saving requires an account: for anonymous visitors the
Create button routes to /login?redirect=/alerts?new=... so the built
alert is created immediately after sign-in. Signed-in users get the
full dashboard. Moved from the auth-gated (app) group into (marketing)
(auth-adaptive header, no forced redirect).
