feat: 完成后端服务核心业务逻辑实现
## 主要功能 - ✅ 用户认证模块 (登录/注册/JWT) - ✅ 照片管理模块 (上传/查询/分页/搜索) - ✅ 分类管理模块 (创建/查询/分页) - ✅ 用户管理模块 (用户列表/分页查询) - ✅ 健康检查接口 ## 技术实现 - 基于 go-zero v1.8.0 标准架构 - Handler → Logic → Model 三层架构 - SQLite/PostgreSQL 数据库支持 - JWT 认证机制 - bcrypt 密码加密 - 统一响应格式 - 自定义模型方法 (分页/搜索) ## API 接口 - POST /api/v1/auth/login - 用户登录 - POST /api/v1/auth/register - 用户注册 - GET /api/v1/health - 健康检查 - GET /api/v1/photos - 照片列表 - POST /api/v1/photos - 上传照片 - GET /api/v1/categories - 分类列表 - POST /api/v1/categories - 创建分类 - GET /api/v1/users - 用户列表 ## 配置完成 - 开发环境配置 (SQLite) - 生产环境支持 (PostgreSQL) - JWT 认证配置 - 文件上传配置 - Makefile 构建脚本 服务已验证可正常构建和启动。
