root 3082148d7e 实现PDMS模型状态API并移除硬编码数据
## 主要改进
- 实现 /api/status/model 接口,返回真实PDMS模型状态信息
- 使用MDB.CurrentMDB、Project.CurrentProject等AVEVA API获取真实数据
- 移除硬编码的CurrentSession、PositionInfo、PdmsSpecific等复杂结构
- 简化数据模型,只保留核心的真实数据字段

## 技术实现
- 通过DbSession获取真实的用户名、会话开始时间和持续时间
- 通过WorldMembers()获取真实的模型元素统计
- 修复DateTime类型的null合并运算符编译错误
- 清理不使用的方法和类定义

## API返回数据
现在返回的数据主要包含真实的PDMS信息:
- ModelLoaded: MDB连接状态检查
- ProjectName: 真实的设计数据库名称
- MdsName: 真实的MDB名称
- UserName: 真实的数据库会话用户
- StartTime: 真实的会话创建时间
- TotalElements: 真实的模型元素数量统计
