feat: 完善后端架构 - 标准化Controller层和Service层
✨ 新功能: - 创建了完整的Service层架构，包含所有业务实体的Service接口和实现类 - 新增8个标准化的Controller类，支持完整的CRUD操作 - 实现了统一的Request/Response模式和分页查询功能 - 创建了认证服务(AuthService)和令牌服务(TokenService) - 添加了Redis配置和认证拦截器 🏗️ 架构优化: - 移除Controller层所有try-catch块，使用全局异常处理机制 - 创建了专门的异常类(AuthException, TokenException, CaptchaException) - 统一了API返回格式，完善了Result类的方法 - 实现了标准的分页查询和参数校验 📦 新增文件: - 8个Controller类: Achievement, Comment, CommunityPost, Conversation, CozeApiCall, EmotionAnalysis, Reward, UserStats - 12个Service接口和对应的实现类 - 标准化的DTO类(Request/Response) - 异常处理类和拦截器 - 测试用例 🔧 重构优化: - 重写了AuthController，移除所有业务逻辑到Service层 - 优化了MessageController，使用标准的Request/Response格式 - 更新了全局异常处理器，支持多种异常类型 - 完善了WebConfig配置，添加认证拦截器 📊 代码统计: - 新增文件: 60+个 - 新增代码行数: 8000+行 - 重构代码行数: 1000+行 - 移除过时接口: 4个
