🚗 feat(sales): listar estoque pelo contexto e reservar veiculos no pedido

Passa a aproveitar orcamento e perfil guardados na conversa para sugerir estoque quando a compra ainda nao tem veiculo definido, preservando a selecao na memoria e guiando o usuario ate o fechamento do pedido.

Tambem impede que veiculos reservados continuem aparecendo como disponiveis, devolve o status do veiculo na resposta deterministica do pedido e amplia os testes de regressao dos fluxos de compra e cancelamento.
