"""admin 上报更低价审核:列表 + 统计(读)+ 通过(发金币)/拒绝(写,带审计)。

数据由客户端 POST /api/v1/report 写入 price_report 表(提交即 pending);本路由是运营后台
对它的人工审核窗口。**通过** → 给上报用户钱包发固定金币(PRICE_REPORT_REWARD_COINS):
改状态 + 发金币(wallet.grant_coins)+ 审计同一事务一起 commit(原子,仿 users.grant_user_coins),
绝不只改状态不发钱或反之。客户端轮询 GET /api/v1/report/records 自动看到结果(无需推送)。
