feat(ai): 支持双模型多视角AI设计生图与后台管理系统

- 实现AI多视角设计图生成功能,支持6个可选设计参数配置
- 集成SiliconFlow FLUX.1与火山引擎Seedream 4.5双模型切换
- 构建专业中文转英文prompt系统,提升AI生成质量
- 前端设计预览支持多视角切换与视角指示器展示
- 增加多视角设计图片DesignImage模型关联及存储
- 后端设计服务异步调用AI接口,失败时降级生成mock图
- 新增管理员后台管理路由及完整的权限校验机制
- 实现后台模块:仪表盘、系统配置、用户/品类/设计管理
- 配置数据库系统配置表,支持动态AI配置及热更新
- 增加用户管理员标识字段,管理后台登录鉴权支持
- 更新API接口支持多视角设计参数及后台管理接口
- 优化设计删除逻辑,删除多视角相关图片文件
- 前端新增管理后台页面与路由,布局样式独立分离
- 更新环境变量增加AI模型相关Key与参数配置说明
- 引入httpx异步HTTP客户端用于AI接口调用及图片下载
- README文档完善AI多视角生图与后台管理详细功能与流程说明
