🐛 fix(posts): 添加错误日志输出以便调试

- 在获取帖子列表接口的错误捕获中添加console.error输出错误信息

♻️ refactor(follows): 修复FollowEntity关联关系定义

- 将follower关联从user.id改为user.following
- 将following关联从user.id改为user.followers

♻️ refactor(posts): 重构帖子服务错误处理方式

- 将HTTPException抛出改为普通Error抛出
- 统一错误消息格式，移除HTTP状态码硬编码

✨ feat(posts): 增强关注动态查询功能与日志记录

- 添加debug日志记录，便于跟踪查询过程
- 分离数据查询和计数查询，优化性能
- 记录生成的SQL和参数，便于调试
- 添加查询结果日志，记录返回数据量

✨ feat(users): 添加用户关注关系的反向关联

- 为UserEntity添加following和followers一对多关联
- 实现用户关注列表和粉丝列表的查询能力
