feat: 统一页面调度体系 — 全局互斥 + 动态尺寸 + 账户信息页

PageDispatcher 重构：
- singleton + floatingPanels[] 双状态 → 单一 activePanel 状态
- 全局互斥：已打开面板时禁止打开新面板（保留拖拽/图片拖放等互操作）
- 占位组件预计算为模块级 Map，消除 ESLint static-components 误报
- PAGE_MAP 支持 width/height 配置，动态函数计算（视口比例自适应）
- 容器默认尺寸改为动态：Modal=min(w*0.55,720) Drawer=min(w*0.38,520)
- 修复 FloatingPanel 未接收 width/height 配置的问题

Test2 账户信息页：
- AuthAPI.getUserInfo() → 三卡片布局（积分/套餐/今日统计）
- 加载态 Skeleton / 错误态 Result+重试
- centToYuan 积分转换、formatDate 日期格式化

目录调整：wechat-work/ → headers/
