feat(cps): 后端接入淘宝/京东多平台(payload + 群多平台 + 复制统计 + 迁移)
- model: cps_group.platforms 多选 / cps_activity.payload(淘口令/京东链接) / cps_link.sid 可空 + 复制统计 - admin API: 群与活动平台多选、批量生成落地页短链 referral-links、对账字段可空 - 落地页 cps_redirect: 淘宝展示淘口令(记 copy 事件) / 京东 302 / 美团原逻辑 - 迁移 cps_v2_platforms: 加 platforms/payload/event_type 列, sid 放宽可空(含 downgrade) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
