fix: improve file manager command handling

1. Changed command strings to QStringList for better argument handling
2. Fixed typo in pin_screenshots module (changed "select how-item" to
correct "--show-item")
3. Improved consistency across different modules for file manager
commands
4. Added missing QtCore/qcontainerfwd.h include for QStringList support

These changes make the file manager command execution more reliable and
maintainable by:
- Using proper argument separation with QStringList instead of comma-
separated strings
- Ensuring consistent behavior across different parts of the application
- Fixing a typo that could cause the file manager to fail
- Adding required header for QStringList operations

fix: 改进文件管理器命令处理

1. 将命令字符串改为 QStringList 以更好地处理参数
2. 修复 pin_screenshots 模块中的拼写错误（将 "select how-item" 改为正确
的 "--show-item"）
3. 提高不同模块间文件管理器命令的一致性
4. 添加缺失的 QtCore/qcontainerfwd.h 头文件以支持 QStringList

这些改进通过以下方式使文件管理器命令执行更可靠和可维护：
- 使用 QStringList 而不是逗号分隔的字符串来正确分离参数
- 确保应用程序不同部分行为一致
- 修复可能导致文件管理器失败的拼写错误
- 添加 QStringList 操作所需的头文件
