chore: 前端 cop-task-detail 走 mock + 后端 task_deeplink 同步到 backend/config.yaml

- frontend-web/.env.production: VITE_MOCK_COP_TASK_DETAIL=true（consumer 外网不可达，登录深链任务详情走本地假数据）
- backend/config.yaml: 补上 task_deeplink 段（test/delete_test=true 走 mock），与外层 config.yaml 对齐；服务器实际加载的是 backend/config.yaml，否则 /api/public/config/task-deeplink 返回空导致 rwfx 目的树闸门失效
