拆分 service 与前端大文件,修复 CORS 配置与格式问题

- 后端 internal/service 按职责拆分: fulfillment.go(1397→527)拆出 wallet/timeout/data/order/query/dashboard/shipnotify delivery.go(1124→801)拆出 upstream/link/state/helpers merchant.go(855→251)拆出 member/product/api_client/catalog/helpers - 前端 MerchantCenter.tsx(1327→606)拆出 merchantCenterTabs/merchantCenterUtils - docker-compose backend 透传 CORS_ALLOWED_ORIGINS - CORS 白名单实现(config/router/README/.env.example 配套) - 修复 gofmt 与文件尾部多余空行
