fix(test-round): 测试清单一批 bug 修复 + 团队月限额持久化

后端:
- accounts: 团队级月限额持久化(Team.monthly_credit_limit 三态 + PATCH/GET
  /api/auth/team/settings/,刷新不丢,PMC#12);头像上传 500→502 可读错误;
  设备下线真失效(删并重建 token,旧 token 401)
- assets: 审核类目加 model_portrait,消除三视图"无需审核"误报
- ai/projects/products: 模特已有三视图复用、产品三视图同步回商品库
  (metadata.view=three_view)、真人模特三视图回写

前端:
- 商品图删除判断改用真实图片数;团队成员弹窗禁点外部关闭
- 图片预览骨架铺满占位;平台套图左侧栏折叠改导航同款;收件箱长文换行对齐
- 团队月限额改真落库(乐观更新+失败回滚)

测试:新增 TeamSettingsTests(5 条),accounts 全套 36 tests 通过;前端 build 0 error
