Link para baixar um material

POST

/v1/knowledge/materials/{materialId}/download-url

curl --request POST \
  --url https://developers.nexo.winningsales.com.br/v1/knowledge/materials/example/download-url \
  --header 'Authorization: Bearer <token>'

URL assinada da versão atual, válida por 5 minutos, que baixa o arquivo com o nome original. Como no app, vale para todo o time, porque o Copiloto e a busca na base citam materiais para o vendedor; cada link fica na atividade da API. O arquivo nunca passa pela API: o envio e o download são por link assinado do armazenamento, e cada link gasta a classe file (60 por minuto na empresa, 30 por token).
