feat(ai-optimized-editor): Add AIDisplayButton and store to add feature to view last AI generated optimized code

- 添加 AIDisplayButton组件，用于切换 AI 优化代码和原始代码
- 修改 AIOptimizeButton 组件，仅在非 AI 编辑模式下显示
- 在代码工具栏中集成 AIDisplayButton
- 更新 problem-editor store，添加 AIgenerate 和 LastOptimizedCode 状态
-优化 AIEditorWrapper 组件，支持生成优化代码和回退功能
