feat(api): 添加图像处理配置和服务器端图像处理功能

- 新增 CompressionConfig、ThumbnailConfig 和 ImageProcessingConfig 结构体用于图像处理配置
- 实现 GetEffectiveConfig 方法提供图像处理配置的默认值
- 在 UploadConfig 中添加 ImageProcessing 字段传递服务器配置
- 移除客户端本地缩略图生成功能，改用服务器端处理
- 添加 UploadFaceDataWithProcessing 函数实现带图像处理的上传流程
- 实现 configToImageOptions 函数将服务器配置转换为图像处理选项
- 在 util/image.go 中添加完整的图像处理功能，支持裁切和缩放模式
- 更新依赖添加 golang.org/x/image 用于高质量图像缩放
- 添加 .claude 到 .gitignore 文件
