Introduce category-level name/description translations in the cookie
banner i18n flow. Seed default translations for fr/de/es on banner
creation, parse them from the stored JSON, and manage them via
react-hook-form Controllers instead of a manual ref/callback pattern.
Enhance the panel preview with category descriptions and all three
action buttons.
