feat: 更新数据库结构和链接任务逻辑

主要修改:
1. 更新`game.sql`文件，添加`system_config`表并调整多个表的`ENGINE`和`AUTO_INCREMENT`设置。
2. 在`LinkTask`实体中新增`completedPoints`字段，更新状态字段以包含`COMPLETED`状态。
3. 在`LinkTaskMapper`中新增根据设备ID和状态查询链接任务的方法。
4. 在`LinkStatusService`中更新状态描述映射，增加对`COMPLETED`状态的处理。
5. 在`DeviceStatusService`和`ScriptClient`中新增解析设备状态的方法，支持检查设备是否完成游戏。

技术细节:
- 通过数据库结构的更新，增强了系统的配置管理和链接任务的状态处理能力。
- 新增的功能支持更灵活的设备状态监控和任务管理。
