fix: 修复火山云API调用问题 - 添加文件上传到云端功能

问题修复:
- 火山云API需要HTTPS URL，不能使用本地文件路径
- 添加CloudUploadService集成，在调用API前先上传文件到云端
- 修复image_url和driving_video_url使用本地路径的问题

技术实现:
- 集成现有的CloudUploadService到VolcanoVideoService
- 在call_volcano_api方法中添加文件上传逻辑
- 先上传图片和驱动视频到云端，获取HTTPS URL
- 使用云端URL调用火山云API，确保API调用成功
- 添加详细的上传进度日志和错误处理

修复的错误:
- 400 Bad Request: image format unsupported: invalid image url
- 错误原因: 使用了本地文件路径 'c:\\Users\\...' 而非HTTPS URL
- 解决方案: 自动上传文件到云端并获取可访问的URL
