refactor: 重构配置管理，移除.env依赖，使用docker-compose环境变量+Nacos配置中心

- 更新所有application-prod.yaml，将环境变量占位符替换为硬编码默认值
- 重写docker-compose.core.yml，使用Spring Boot环境变量命名规范
- 修复Jenkins pipeline中的getContainerName方法调用错误
- 配置优先级：Nacos配置中心 > Docker环境变量 > application-prod.yaml

变更文件：
- viewsh-gateway/src/main/resources/application-prod.yaml
- viewsh-module-system-server/src/main/resources/application-prod.yaml
- viewsh-module-infra-server/src/main/resources/application-prod.yaml
- viewsh-module-iot-server/src/main/resources/application-prod.yaml
- viewsh-module-iot-gateway/src/main/resources/application-prod.yaml
- docker-compose.core.yml
- Jenkinsfile
