实现Creo模型保存功能接口

新增功能:
- 添加SaveResult结构体用于保存操作结果
- 实现CreoManager::SaveModel()方法，使用OTK pfcModel::Save() API
- 添加SaveModelHandler HTTP路由处理器
- 注册/api/model/save接口支持POST请求

技术特性:
- 简化设计：只保存当前模型到原位置，无复杂另存为逻辑
- 完善的OTK异常处理：支持BadInputs、GeneralError、InvalidName等
- 标准JSON API格式：返回文件大小、保存时间、软件信息等
- 与现有架构完全兼容：不影响任何现有功能

API使用:
POST /api/model/save
请求: {"software_type": "creo"}
响应: 包含file_size、save_time、software、original_file等信息
