feat(core): 列表数据在途显示骨架屏(加载态),不再先显示空状态

渐进渲染后,列表在接口返回前会短暂显示「0 SKU / 显示 0」的空状态,易被误读为「没数据」。
新增 SkeletonGrid/SkeletonRows(components/loading),区分「加载中(请求在途且无数据)」与
「加载完确实为空」:

- 全局态页(商品库/视频项目/工作台最近项目):App 传 loading={!dataLoaded},未加载完显示骨架。
- 自取页(资产库/商品详情AI素材/图片生成任务/账单流水):各自 loading 标志,首次拉取时显示骨架/加载行。
- 团队成员有 owner 兜底行(非空)不改。

闸:9 页全绿、功能正常;实测 /products 加载期显示骨架→数据到后渲染真实卡片。
