feat(note): 新增笔记删除功能

- 新增 DeleteNoteReqVO 请求参数类，用于接收笔记删除请求
- 在 NoteController 中添加 /delete 接口，实现笔记删除功能
- 在 NoteService 和 NoteServiceImpl 中实现 deleteNote 方法
- 删除笔记时进行权限校验，仅允许笔记创建者删除
- 删除操作为逻辑删除，更新笔记状态为已删除
- 删除笔记后清除 Redis 缓存，并通过 MQ 广播通知各实例清除本地缓存
-优化更新和可见性接口的权限校验逻辑，避免重复代码
- 添加 MQ 测试类 MQTests，用于批量发送关注/取关消息
- 引入 Guava 的 RateLimiter 实现 MQ 消费端限流- 配置 Nacos 配置中心依赖及动态刷新配置
- 更新 .gitignore 文件，忽略日志文件目录
- 在 application.yml 中添加 MQ 消费者限流配置项
- 在 bootstrap.yml 中完善 Nacos 配置中心相关配置
- 为 FollowUnfollowConsumer 添加限流逻辑，防止消费端压力过大
