Consolidate the separate Cookies tab into the Display page so
categories with full cookie CRUD, reordering, and theme preview
live together. Delete the now-redundant CookieBannerCookiesPage,
its loader, route, and nav tab.
Add row actions (edit, move-to-category, exclude, delete) to the
detection page. The move-to-category dropdown uses an
interaction-triggered preloaded query following the
useQueryLoader pattern. Document this pattern in the
react-components guide.
