admin 反馈/低价审核接口增强 + 反馈采集端环境(版本/机型)

- 反馈:新增 GET /admin/api/feedbacks/summary(待审核/已采纳/未采纳/合计计数);
  列表联表带出完整手机号 + 昵称(供 admin 点手机号查该用户全部反馈)
- 低价审核:列表加 sort_by/sort_order(提交时间排序);联表带出手机号/昵称,
  并按 comparison_record_id 关联比价记录带出 trace_id/trace_url + 机型/ROM/Android/app 版本
- feedback 表新增 app_version/device_model/rom_name/android_version 四列 + alembic 迁移;
  /api/v1/feedback 提交接口接收并落库,供 admin 反馈页展示「提交版本号」「机型OS版本」
  (字段可空,旧端不传不影响提交)
