fix(carousel): enviar interactiveMessage direto + biz node + sem viewOnceMessage

Ajuste na estrutura do carrossel para renderizar na Web:
1. Removido viewOnceMessage wrapper - carrossel usa interactiveMessage direto
2. Biz node habilitado com native_flow v=9 name=mixed
3. Removido subtitle vazio e header vazio do nível raiz
4. Sem bot node (já estava correto)
