feat: 添加用户端链接状态查询接口及自动刷新逻辑

主要修改:
1. 在LinkController中新增获取用户链接状态的接口，支持通过linkId或codeNo查询。
2. 在LinkStatusService中实现用户链接状态查询逻辑，包含自动刷新和二维码更新功能。
3. 更新LinkTask实体，添加needRefresh、refreshTime、qrCreatedAt和qrExpireAt字段以支持新功能。
4. 在ScriptClient中新增检查空闲设备、选区、刷新、检查上号状态等操作的实现。
5. 更新SecurityConfig，允许用户端获取链接状态接口公开访问。

技术细节:
- 新增UserLinkStatusResponse DTO以支持用户链接状态的返回格式。
- 通过脚本端接口实现链接状态的自动刷新和二维码信息更新。
