fix(v0.11): 第二轮走查 P1/P2（按模块优先级）

- davinci：DavinciResult.fail/success；FileManager Feign Fallback 结构化降级；FileStorageManagerImpl 对空 Result/Response 防御
- cwos-resource：RestPortalUserServiceImpl 消除静默 null，统一 CloudwalkResult.fail 与 getDefaultPwd 空串语义
- device-manager：DeviceConstant 改为 final 工具类
- aks：AksRespCodeConstant final + 私有构造
- ninca-crk：启动入口 SLF4J、显式 Feign 扫描包、SpringApplication 写法
- ninca-qk-alarm：main 简化、收窄 @EnableFeignClients（保持 netflix 注解以兼容当前 BOM）
