feat: 图片创作每张图加「加入模特库」按钮 (row41)

图片工作台单图「更多」气泡新增「加入模特库」(与「加入资产库」并列):
把该生成图复用为模特形象图建 Model 条目,加入后变「已加入模特库」禁用。

后端新增 POST /api/models/enroll-asset/(ModelLibraryViewSet.enroll_asset):
复用已有资产作 portrait_asset 建 Model,不重新上传/不二次扣费;同一资产幂等返回。
需部署生效(后端)。

构建: tsc --noEmit=0, npm run build=0; 后端 py_compile OK。
