feat(ad-revenue): admin 广告收益报表(按 用户/日期/类型/应用/代码位 聚合)

- 新增 GET /admin/api/ad-revenue-report:展示条数/收益 + 复用金币审计逐条复算做发奖对账
- ad_ecpm/ad_reward/ad_feed_reward 各加 app_env + our_code_id 两列(alembic 迁移)
- ecpm-report / feed-reward 接收并落库 app_env/our_code_id;激励发奖按 ad_session_id 回填
- ad_audit 抽出 audit_rows,报表与逐条审计复用同一复算口径
- 组级 matched 改「组内逐条全一致」,避免应发和==实发和的互相抵消掩盖错误
- list_feedbacks 改 offset 分页并返回 total(配合 admin 页码分页)
- 反馈正文上限 _CONTENT_MAX 2000→200
- 文档:新增 admin-ad-revenue-report,更新 ecpm/feed-reward/feedback 及对应 db docs
