feat(badges): 添加用户勋章系统，支持睡眠挑战勋章自动授予

实现完整的用户勋章功能模块：
- 新增 BadgeConfig 和 UserBadge 数据模型，支持勋章配置和用户勋章管理
- 新增 BadgeService 服务，提供勋章授予、查询、展示状态管理等核心功能
- 在挑战服务中集成勋章授予逻辑，完成首次睡眠打卡授予 goodSleep 勋章，完成睡眠挑战授予 sleepChallengeMonth 勋章
- 新增用户勋章相关接口：获取用户勋章列表、获取可用勋章列表、标记勋章已展示
- 支持勋章分类（睡眠、运动、饮食等）、排序、启用状态管理
- 支持勋章来源追踪（挑战、系统、手动授予）和元数据记录
