feat(puzzle): 新增微信小程序二维码生成功能

- 在DataSourceContext中新增scenicId字段用于景区关联
- 实现WechatQrcodeDataSourceStrategy策略类，支持生成并上传微信小程序码
- 扩展DataSourceType枚举，增加WECHAT_QRCODE类型
- 修改PuzzleElementFillEngine执行方法，支持传入scenicId参数
- 在PuzzleGenerateServiceImpl中集成二维码自动生成逻辑
- 新增generateWechatQrcode方法用于生成并上传小程序码到OSS
- 完善日志记录和异常处理机制
- 添加必要的工具类和存储服务依赖注入
