fix: 修复 OmniHuman 主体识别图片上传问题

问题修复:
-  修复本地文件路径无法被火山云 API 识别的问题
-  添加图片先上传到云端再调用识别 API 的完整流程
-  集成 fileUploadService 实现图片云端上传
-  添加上传进度显示，提升用户体验

技术改进:
- 使用 fileUploadService.uploadFileToCloud() 上传图片
- 获取云端 URL 后调用火山云识别 API
- 添加详细的进度反馈 (上传 60% + 识别 40%)
- 完善错误处理，区分上传失败和识别失败

现在用户可以正常使用 OmniHuman 主体识别功能了！
