feat(comment): 新增评论热度计算与更新功能

- 在评论数据对象中新增 childCommentTotal 和 heat 字段
- 扩展 CommentDOMapper 支持批量更新评论热度值
- 新增 CommentHeatBO 类用于封装评论热度信息
- 实现基于点赞数和回复数的热度值计算工具类 HeatCalculator
- 添加 RocketMQ 消费者异步处理评论热度更新消息
- 引入 buffer-trigger依赖实现消息聚合发送
- 扩展 JsonUtils 工具类支持 Set 类型反序列化
- 新增 MQ 常量 TOPIC_COMMENT_HEAT_UPDATE用于热度更新主题
- 修改 SQL 脚本增加 heat 字段并设置默认值- 更新测试接口请求参数内容以适配新逻辑
