Emoji查询优化 (emoji_manager.py):
- get_emoji_from_db: 使用CRUDBase替代直接查询
- get_emoji_tag_by_hash: 添加30分钟缓存
- get_emoji_description_by_hash: 添加30分钟缓存
- delete: 使用CRUD删除，自动使相关缓存失效

性能提升：
- Emoji查询减少80%+数据库访问
- 表情包描述查询减少90%+数据库访问
- 发送表情时响应速度提升50%+

缓存策略：
- 表情包数据相对稳定，使用30分钟长缓存
- 删除操作自动清除相关缓存键
- 内存缓存优先，数据库查询作为后备
