- 后端:claim 详情分流 affiliate_dash 分支 + 详情轮询刷新 bind-result
- 输 UID 触发 bind(拿 bindUuid/二维码, task→waiting_binding)
- 新增 POST /claim/:token/affiliate-dash/submit(submit→redeeming + 事件)
- 前端:ClaimAffiliateDashSteps(二维码/绑定状态/mismatch警告/提交发货)
- claim-snapshot/claim-poll 按 flowType 分流(step2 绑定中/step3 已绑定待提交/step4 结果)
- 前后端 typecheck + 后端 212 测试通过
