feat: 完善PhotoRepository时间处理和数据库优化
主要改进: - 增强PhotoRepository时间字段处理 * 添加TakenAt(拍摄时间)和LastModified(修改时间)字段 * 实现parseExifDateTime函数支持多种EXIF时间格式 * 优先使用EXIF拍摄时间,备选文件修改时间 * 支持带时区和不带时区的时间格式解析 - 新增时间相关查询方法 * GetPhotosByTakenDateRange - 按拍摄时间范围查询 * GetPhotosByModifiedDateRange - 按修改时间范围查询 * GetRecentPhotosByTaken - 获取最近拍摄的照片 * GetOldestPhotosByTaken - 获取最早拍摄的照片 * GetPhotosWithoutTakenDate - 获取没有拍摄时间的照片 - 优化CreatePhotoFromImageAPI方法 * 智能提取EXIF中的时间信息 * 自动计算宽高比 * 处理文件创建时间 * 完善错误处理和日志记录 - 改进图像任务工作流 * 简化saveToDatabase方法的Photo保存逻辑 * 增加时间信息的详细日志记录 * 移除冗余的数据设置代码 * 提高代码可维护性 - Photo表模型完善 * 添加时间相关字段的数据库标签 * 优化字段类型和约束 * 支持时间索引查询 技术特点: - 支持多种EXIF时间格式的自动识别和解析 - 智能的时间优先级处理策略 - 完整的时间范围查询API - 详细的操作日志和错误处理 这些改进为照片的时间管理和查询提供了完整的解决方案, 支持按时间维度进行照片组织和检索。 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
