refactor: Home 模块 VCHSM 三栏重构 + Services 迁回 + 右键菜单体系 + 公告修复

## Home 模块三栏 VCHSM 重组
- 按渲染归属重新分配文件：ModelSelector/TaskHistory → left/，ModelInputForm/widgets → center/，OutputPreview → right/
- BannerCarousel 移至 shared/views/（全局组件）
- controls/ → widgets/ 重命名，消除与 controllers/ 的命名歧义
- 新增 barrel 文件（left/center/right/shared 各级 index.ts）

## Services 层迁回 src/services/modules/
- 全部 API 类型定义与请求函数从 modules/*/controllers/ 迁回 services/modules/{domain}/
- 恢复原始文件名（model-api.ts → models.ts，task-api.ts → task.ts 等）
- 新增 domain 子文件夹（home/auth/announcement/account）
- 更新全局 ~70 处导入路径

## TaskHistory 提取 Controller + Hook 层
- 新建 left/controllers/task-table-config.ts（常量 + 纯工具函数，零 React 依赖）
- 新建 left/hooks/useTaskTable.tsx（状态管理 + 数据获取 + 列定义 + 滚动同步）
- TaskHistory.tsx 从 915 行精简为 265 行纯视图

## 右键菜单体系完善
- 共享 <ContextMenu> 组件（antd Dropdown 封装，防 Select 冲突）
- 四组菜单定义：任务列表 / 文本输入 / 媒体参考 / 预览区域
- 统一的 ContextMenuItems → AntD MenuProps 转换

## 公告功能修复
- useAnnouncements 增加 isLoggedIn 登录门控，避免未登录时 401 双重请求
- 抽屉打开时触发 refetch()，确保拿到最新数据
