Bring the home product tile to search and explore: seller brand chip
(SellerChip) plus price/discount overlay, instead of a bare image.
- search: map discountPercent/discountPrice/basePrice + sellerName from
ProductSearchResult (sellerName is already returned, so the chip shows
now with the initial-letter fallback).
- explore: map sellerName/sellerLogo/sellerUsername (and add them to the
Product type); these populate once the backend ProductSerializer change
ships.
