/**
|
||
* 修复寄卖「改价上限」被寄卖数量放大的历史数据。
|
||
*
|
||
* 背景：模板驱动规格曾是 unit 计价模板「模板单价 × 寄卖数量」写进 price_cap_fen，
|
||
* 但售价/库存/匹配引擎都是单价口径，导致改价弹窗提示的上限是单价的 N 倍。
|
||
* 取价逻辑已改为按单价返回；本脚本把历史脏数据修正为单价。
|
||
*
|
||
* 只处理命中 bug 特征的行：price_cap_fen === 单价 × quantity 且 quantity > 1。
|
||
* 默认 dry-run（只打印），加 --apply 才写库。
|
||
*
|
||
* 用法（apps/backend 目录下）：
|
||
* npx tsx scripts/fix-consignment-price-cap.ts
|
||
* npx tsx scripts/fix-consignment-price-cap.ts --apply
