feat: 优化前端loading状态和用户体验

- 新增MaterialCardSkeleton骨架屏组件
- 优化MaterialImportDialog的进度显示
- 添加详细的导入进度动画和状态指示器
- 改进项目统计信息的loading状态
- 新增LoadingState通用加载组件
- 优化按钮状态和禁用逻辑
- 改进空状态显示和交互

UI/UX改进:
1. 骨架屏loading：替换简单spinner为详细骨架屏
2. 进度指示器：添加阶段指示器和动画效果
3. 状态反馈：实时显示当前处理文件和进度
4. 按钮状态：导入过程中禁用相关按钮
5. 视觉优化：添加图标、颜色和动画效果
