fix(n8n): responde de forma sincrona (texto puro) e usa memoria simples

Browse Source 
O Z-PRO captura a resposta HTTP do webhook e reenvia direto ao cliente
(variavel n8n1 -> passo Mensagem), entao o envio assincrono via API duplicava
a mensagem. Troca para responseMode: responseNode + Respond to Webhook em
texto puro, remove o node de envio assincrono, e troca a memoria de sessao
de Postgres (reservado para outro fluxo) para o node Simple Memory nativo.
