fix: 测试清单(8) 新一轮 — ZWQ/PMC/设置/团队 多项修复

视频/工作台/商品库(ZWQ):
- row19 视频阶段移除已取消的【上传视频】按钮 (pipeline.tsx)
- row20 工作台统计栏(总项目/进行中/成片)点击跳转视频项目对应 tab (dashboard/projects/route-config/App)
- row21 最新项目跳转改用真实 projectId, 不再跳到最近打开项目 (dashboard.tsx)
- row22+PMC28 网格/列表视图模式持久化(localStorage), 跨菜单记住用户选择 (projects/ai-tools + 新 hook use-view-mode.ts)
- row24 已有三视图的演员/模特直接复用, 不再强制点AI生成三视图 (pipeline.tsx)

图片生成/设置(PMC):
- row27 任务中心: 6个进行中状态补全归类, 不再把生成中误判为失败栏 (stage-config.ts)
- row29 头像上传500: avatar_url 存公读直链替代超长预签名URL(URLField max_length=200溢出) (accounts/views.py, 需部署)
- row30 显示名保存后回显: 改读 first_name 回退 username, 修刷新仍旧名 (settings.tsx)
- row31/32 隐藏【创作默认】【显示】两个设置模块 (settings.tsx)

平台套图(YYX):
- row3 图片预览铺满占位 (ai-tools-page.css)

团队:
- PMC25 充值/邀请成员/设置月限额三弹窗禁止点遮罩误关 (team.tsx)

含平台套图线上提示词优化(services.py/views.py/api.ts, 前序会话遗留一并提交)
构建: tsc --noEmit=0, npm run build=0 (1755模块); 后端 py_compile OK
注: row29 头像/后端项需部署生效
