feat(catalogo): link de afiliado por idioma e botão alinhado no rodapé do card

O botão do AliExpress passa a ficar no rodapé do card, alinhado entre os cards.
O link usa a coluna Link_<idioma> da planilha (en, es, fr, de, zh-CN) e cai no
Link (Brasil) quando ela está vazia. Colunas de link não viram filtro, e a API
lê A1:AZ1000.
