feat(cache): 优化设备模板缓存策略并添加分布式缓存清理功能

Browse Source 
- 引入Caffeine本地缓存替代Redis缓存提高性能
- 添加Redis Pub/Sub机制实现多节点缓存同步清理
- 在CsDeviceServiceImpl中注释掉原有的Redis缓存清理逻辑
- 在CsDevModelServiceImpl中添加缓存清理消息发送功能
- 新增ModelCacheClearListener监听器处理缓存清理通知
- 实现IStatService接口的clearModelCache方法
- 添加getModelData方法实现本地缓存优先的数据获取策略
- 配置最大50000条缓存数据，60分钟过期时间
