fix: 优化Pub/Sub API实时数据同步实现

主要变更：
- 修复了导入包错误，将com.salesforce.eventbus改为com.salesforce.multicloudj
- 重命名PubSubClient为SalesforcePubSubClient，避免与依赖包中的类冲突
- 更新了所有相关文件中的引用，确保使用正确的包和类
- 修复了EventSubscriberImpl.java中缺少的导入语句
- 优化了错误处理和日志记录

技术改进：
- 确保使用正确的Pub/Sub API客户端库
- 提高了代码的可维护性和可读性
- 修复了潜在的运行时错误
- 完善了异常处理机制
