perf(core): 全站资产改服务端懒加载,撤掉 bootstrap 全量 allAssets

不再在启动时一次性拉全部资产(数据多时随之变慢/串多页),各页按需服务端分页/过滤:
- 生图(ImageWorkbench 模特库按 category=person、AssetFactory 按 ai 生成图)页面内懒加载。
- 商品库/项目向导封面图改用后端内嵌 cover_preview_url / images[].preview_url,不再反查全局 assets。
- 商品详情 AI 素材按 ?product 懒加载(上传/生成/采用三视图后刷新)。
- 工作台资产总数走轻量 /assets/summary/。
- App bootstrap 删除 api.allAssets() 与全局 assets state;loadData 仅留必要全局数据。
- 后端 ?product 过滤并集补上 ProductImage 关联资产,等价前端原 belongsToProduct。
- pipeline 用项目详情已内嵌的 *_url 显示,调用处传空 assets(不再依赖全局全量)。

闸验证:9 页功能正常、无分页瀑布、无接口报错;首屏不再含资产全量拉取。
