Generalize the cursor Prev/Next pagination hook into a reusable
useCursorPagination in lib/relay, taking the page size as a parameter,
and keep the updates page size (25) as a feature constant.
Move the list card surface and its loading-dim state into tv variants
behind an UpdatesList component, and lift the detail article layout and
its gold metadata styling into shared variants, so the pages carry only
placement classes. Skeletons reuse the same variants.
Relocate the generic pager labels to the app-root namespace and expose
Intl.DateTimeFormat options on the formatDate helper.
