feat: 完善工作空间文件操作功能

新增功能：
- 重命名弹框（替换 alert）
- 新建文件/文件夹弹框
- 上传文件功能
- 移动文件功能（树状选择+确认）
- 查看文件详情弹框
- 刷新文件列表按钮

交互优化：
- 修复操作按钮 toggle 行为
- 右键菜单分组显示（基础操作/详细信息/危险操作）
- 预览弹框宽度调整为 600px
- 不支持预览的文件类型 Toast 提示
- 文件树子项缩进 16px
- 空文件夹展开后直接为空

数据增强：
- 中文文件名示例
- 无法预览类型示例（压缩包、数据库、二进制）
- 多级文件夹嵌套示例
- 空文件夹示例

样式新增：
- 标题栏操作按钮样式
- 刷新按钮旋转动画
- 新建按钮下拉菜单
- 右键菜单分组分隔线
- 空状态样式
