feat(ad): 信息流广告切换为 Draw 信息流并区分比价/领券收益

后端支持 Draw 信息流广告:
- ad_feed_reward_record 新增 ad_type(feed/draw),ad_ecpm_record 新增 feed_scene(comparison/coupon/welfare)+ Alembic 迁移
- ecpm-report / feed-reward 接口接收并落 ad_type=draw 与 feed_scene
- 广告配置字段 compare/coupon_feed_code_id 改名为 compare/coupon_draw_code_id(默认 Draw 位 104098712)
- 收益报表与对账(ad_revenue / ad_audit)支持 draw 类型,按 feed_scene 区分比价/领券收益
