fix: YYX测试清单16条收口——资产库弹窗层级/批次多选删/商品筛选/模特卡单卡化/垃圾桶清空等

- 资产库:批次弹窗降层(under-confirm 990<999)修单图删除确认弹窗被压;编辑态批次卡多选批删;facets 新增 products 关联商品筛选(前后端,+2 测试);视频成品 tab 补搜索/排序/分页
- 平台套图工作台:「更多」气泡与 icon 左对齐+鼠标移出自动收起;模特卡改单卡(空态「+」占位,点卡进模特库单选回填)
- 工作台:删余额条,冻结/共计移至小标题行右侧(.dash-funds-mono)
- 模特库:点模特卡弹详情(形象图/标签/三视图+灯箱放大)
- 垃圾桶:新增「全部恢复」/「清空垃圾桶」(清空二次确认)
- 视频项目页:字重/阴影等轻量对齐设计规范
- api.assetFacets 返回体逐键兜底:旧后端缺 products 键会致资产库整页 undefined.find 白屏(前后端部署时序防护,浏览器已复现验证)

验证:tsc --noEmit / vite build / apps.assets 测试全过;暂存树已独立编译验证,不依赖工作区其余在途改动
