feat(admin): 用户管理新增用户明细抽屉，聚合资金与交易全链路数据

- 用户管理操作列新增「明细」入口，抽屉按权限提供 5 个 Tab：钱包流水、订单记录、提现记录、邀请返利、支付记录
- 后端：后台订单列表新增 user_id 精确过滤（owner_id / renter_id），邀请关系与返利流水新增 inviter_id / invitee_id 过滤
- 修复：返利流水的「被邀请人手机号」筛选此前后端未实现，一直无效
- 资金流水页、支付记录页支持 ?user_id= 预填，可从明细直达
- 顺带将 invitation/dto.go、repository.go 中两处既有缩进错位按 gofmt 规整
