修复: GET /v1/admin/promo/price/list 字段不匹配导致 400

前端发 rule_id/subscribe_id (均可选), 后端 API 定义为 promo_rule_id
(required), 直接返回 "PromoRuleId is a required field"。

对齐前端约定 (与 usage/list 命名一致):
- API: promo_rule_id(required) → rule_id + subscribe_id, 均可选
- model.QueryPriceList: 改为接 PriceFilter, 按条件过滤
- 同步 fake mock 与校验测试签名
