feat: 新增消息Outbox机制、雪花ID配置优化及多项功能完善

1.  新增数据库唯一约束和Message_Outbox表脚本
2.  新增雪花ID、Hangfire存储、MQ重试等配置实体
3.  重构各项目雪花ID生成逻辑，改为从配置读取WorkerId
4.  优化积分服务分页查询、用户背包更新逻辑
5.  新增JWT令牌Redis过期刷新逻辑
6.  完善RabbitMQ死信队列消息头信息
7.  新增可靠MQ消息发布服务和Outbox派发后台服务
8.  替换原有RabbitMQ直接发送为Outbox可靠发布
9.  优化签到服务逻辑，新增重复签到校验和补签卡扣减逻辑
10. 修复自动铺码消费逻辑，新增点阵页预占和释放机制
