fix: 修复秒杀活动发布后状态未更新的问题

根因：publishFlashSale() 只做了缓存预热，从未调用 updateStatus()
将状态从1（未开始）更新为2（进行中），导致发布后UI无变化，
且活动无法被"进行中"查询找到。

修复内容：
- publishFlashSale() 添加 updateStatus(id, 2) 和缓存更新
- 简化 getFlashSaleList 状态查询，直接按 status 字段过滤
- 新增 findByStatus 仓库方法
- 前后端全面支持 PAUSED(status=4) 状态
- 修复管理后台"恢复"按钮错误显示在"已结束"状态上
