fix(admin): 会员中心等级列表/统计/升级记录N+1三处修复

- MembershipCenter.vue: loadLevels/loadOverview 的 request 拦截器返回结构判定错误
  (listMembershipLevels/getMembershipStats 走拦截器返回已解包 {code,data}，
   误按裸 axios 判定 res.data.code) 导致等级配置列表永远为空、统计卡不更新
- StatsController: freeCount 查询 .or() 位置错误导致恒为 0，改为嵌套 and(w->eq.or.isNull)
- upgrade-records 后端批量填充 userName，消除前端逐条调 user/search 的 N+1 请求
- 删除测试中引用不存在方法 getAdvicesForLowScores 的死桩，恢复 testCompile
