优化：文件服务器安全重构+编辑器增强+搜索排序+更新面板Markdown渲染

- 路径校验提取validateFilePath+sentinel error替代字符串匹配
- requireUpdateAPI收敛7处重复nil检查
- 端口18765统一为8073，消除分散魔法数字
- CodeMirror添加搜索功能+滚动位置LRU缓存恢复
- 文件列表新增列排序+搜索过滤
- Toolbar重排：快捷访问内嵌+搜索框集成+历史改图标
- 重命名零闪烁：updateFilePath草稿迁移
- changelog用marked渲染+sanitizeHtml防XSS
- MigrateTabConfig扩展map驱动覆盖openclaw-manager→version迁移
