优化：CSV编辑模式/PDF导出重构/收藏夹bug修复/移除useLocalStorage

- FileEditorPanel: CSV新增预览/编辑切换、PDF导出；提取openPrintWindow公共函数
- useFavorites: 修复find回调中fav变量遮蔽bug（f.path）、sort改为副本排序
- useFavoriteFiles/DeviceTest: 移除useLocalStorage抽象层，直接管理localStorage
- system.ts: createDir/createFile签名改为(parent, name)两参数拼接
- useFileOperations: createNewFile移除无用content参数
- 清理OpenClaw相关Wails绑定
