Pull real data for desk pages

[maquchizi]

Summary

• Wire content desk pages (/fact-checks/[desk]) to live Hasura data. The listing fetches that desk's fact-checks (route-scoped, reusing the existing server-side filter + pagination), and the hero gets its own carousel from a per-desk "<Desk Name> — Hero" content list.
• Handle not-yet-authored desk content gracefully: a missing hero list, an empty list, and a fetch error all collapse to one hero empty state (masthead + "No featured fact-checks for this desk yet.", no carousel). The grid's empty message is now filter-aware so empty-with-no-filters doesn't read as "no matches for your filters."
• Extract the duplicated hero carousel and banner shell into shared components/ui/HeroCarousel + HeroBanner; the home and desk heroes are now thin compositions (and drop "use client"). This also collapses the slide/dot key logic into one place.
• Drive-by fixes: carousel keys use story.href + index so duplicate placeholder images/titles can't collide (the warning previously persisted on the dots and on the static fallback); set data-scroll-behavior="smooth" so Next doesn't smooth-scroll during route changes.

Test plan

• Desk page (e.g. /fact-checks/climate-change): title + hero empty state render with no carousel; grid shows "No fact-checks have been published here yet." (desk routes are empty on staging).
• An article slug on the overloaded route still renders the article, not the desk page.
• Filters/pagination on a desk page drive the URL and re-fetch the route-scoped slice.
• Home hero renders title/subtitle/CTA + carousel with no duplicate-key console warning.
• pnpm test (73 pass, incl. new route-clause cases), tsc, biome clean.

Closes #33
