Subject: [PATCH] docs: usar sandbox.mx.ntxpay.com (host real da infra atual)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A infra atual (advanced-cloud/EKS) serve *.mx.ntxpay.com. O host público de
sandbox é sandbox.mx.ntxpay.com (ntxpay-edge -> public-ms, wildcard *.mx TLS).
Substitui sandbox.ntxpay.com em todos os exemplos e no openapi.json.
