fix: 创作页 iframe tab 切换状态保持

使用 v-show 始终挂载方案替代 KeepAlive,解决 iframe 内 H5 状态
在 tab 切换后丢失的问题。Vue KeepAlive 会移动 DOM 导致浏览器
重新加载 iframe 内容,v-show 只切换 CSS display 不移动 DOM。

- PublicLayout 中将 PublicCreate 渲染在 router-view 外部
- v-if 懒挂载(首次访问创建),v-show 控制显隐
- 登出时销毁组件避免数据泄漏
- 添加 RouteMeta keepAlive 类型定义
- 添加 E2E 测试覆盖 5 个 tab 切换场景
