feat(equalize): 添加目标曲线获取及缓存功能

- 新增CurveCache实现Redis曲线数据缓存与分布式锁机制，避免重复请求
- 增加CurveHandler支持目标曲线接口，通过EQ API获取并缓存曲线数据
- Config新增EqualizeConfig配置，支持环境变量动态配置
- Repository新增CurveRepository，按brand和name查询模型与目标曲线数据
- 路由更新，集成/getCurve接口处理目标曲线请求
- OTA模型字段优化，bool类型改为BoolInt，实现数据库int与JSON bool映射
- 统一响应格式，调整response包中OK和Fail函数消息字段命名
- 修改服务端配置默认DB IP，支持Equalize参数传递到路由层
- 新增CSV解析实现，从文件读取测量与目标曲线数据
- 修改OTA处理逻辑，修复定向升级判断bug
- Java层新增EqualizeController和ModelService对应功能，保持客户端接口兼容与调用逻辑一致
