feat: 增强安全性和用户隐私保护

主要改进：

1. JWT 密钥验证增强
   - 添加启动时密钥验证（长度、格式、弱密钥检测）
   - 确保密钥符合安全要求（至少32字符）

2. 资产加密算法升级
   - 从 AES-256-CBC 升级到 AES-256-GCM
   - 提供数据完整性校验（认证加密）
   - 添加加密密钥启动时验证

3. 用户隐私保护
   - 新增 findOnePublic 方法返回公开信息
   - GET /users/:id 根据查询对象返回不同信息级别
   - 查询自己返回完整信息，查询他人只返回公开信息

4. 缓存一致性修复
   - 修复更新用户信息时缓存未正确清除的问题
   - 确保完整信息和公开信息缓存同时失效

5. API 文档改进
   - 为用户查询接口添加详细的隐私保护说明
