// 聚水潭「加工单查询」接入自检脚本
//
// 用法：
//   cd backend
//   node scripts/jst-manufacture-probe.js            # 查最近 7 天
//   node scripts/jst-manufacture-probe.js 14         # 查最近 14 天（内部按 7 天分段）
//   node scripts/jst-manufacture-probe.js 7 904533   # 额外按指定加工单号探测
//
// 作用：
//   1. 校验 JST_APP_KEY / JST_APP_SECRET / JST_ACCESS_TOKEN 是否可用
//   2. 自动探测 4 种签名变体，告诉你 JST_SIGN_VARIANT 该填哪个
//   3. 打印首屏加工单原始结构（含 items 明细的 sku_id / qty / io_qty），用于确认「在途数量」取值口径
