Subject: [PATCH] fix(carousel): viewOnceMessage wrapper sem messageContextInfo
 + estrutura Pastorini
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mudanças baseadas na comparação com Pastorini:

1. Adicionado viewOnceMessage wrapper MÍNIMO (sem messageContextInfo)
   - viewOnceMessage é obrigatório para Web/Desktop renderizar carousel
   - messageContextInfo pode ter causado o erro 479 anterior

2. Removido campos extras que Pastorini não usa:
   - Removido messageParamsJson dos cards
   - Removido messageVersion dos cards
   - Removido carouselCardType (Pastorini não define)
   - Removido header vazio no nível raiz (Pastorini não envia)

3. Estrutura final:
   viewOnceMessage.message.interactiveMessage.carouselMessage
