feat(admin): manage points products and redemptions

Platform operators get a points catalog screen (create, edit, publish and
unpublish products with localized names, points price, stock, and ordering) and
a redemption screen that lists orders and moves pending ones to fulfilled or
cancelled. Both are reachable from the console navigation.
