feat(products): 成片中心 UI 4 大功能升级

1. 封面预览 — 卡片已支持 thumbnailUrl 展示
2. 复核状态标签 — 右上角显示待复核(灰)/已通过(绿)/需修改(红)，点击循环切换
3. 批量操作 — 批量下载改用 batch-download API + job_id 轮询
4. 筛选栏 — 新增按项目、按复核状态筛选 Select

API 层新增:
- updateReviewStatus: PATCH /products/{id}/review
- batchDownload: POST /products/batch-download
- getBatchDownloadStatus: GET /products/batch-download/{jobId}
