🐛 fix(flows): endurecer validacao e preservar drafts

Impede que consultas de estoque caiam no fluxo de compra, evita reaproveitamento implícito de CPF para criar pedidos e mantém drafts quando a execução da tool falha.

Também preserva corretamente o estado de revisão, limpando o draft apenas quando a operação conclui com sucesso ou quando a confirmação pendente passa a ser o estado principal.
