新增 affiliate_dash 回调路由与幂等去重(阶段 5)

- POST /api/v1/open/affiliate-dash:验签 → 查任务(404 重试) → webhook_events 幂等闸门 → 状态同步 - migration 013:webhook_events(provider+event_id 唯一) - task-repo findAffiliateDashTaskByOrder(仿 feifei 同构 SQL) - notify-service:去重闸门在找到任务之后,任务未匹配不被 eventId 永久拦截 - typecheck + 212 测试通过;前置错误分支脚本验证通过
