AT 模式下, seata-server 存在 global_table 状态为 committed 的数据无法删除的情况

### Issue Description

AT 模式下, seata-server 处理 **全局事务提交** 时,

`io.seata.server.session.SessionHelper#endCommitted`

执行到如下步骤时 :

```java
public static void endCommitted(GlobalSession globalSession) throws TransactionException {
globalSession.changeStatus(GlobalStatus.Committed);
globalSession.end();
}
```

如果 **seata-server** 进程异常终止, 会导致 global_table **本次全局事务** 的数据状态一直为 **committed**, 并且无法删除.

### Environment:

- JDK version : 1.8
- Seata version: 1.4.1
- OS : macOS

Start at io.seata.server.session.SessionHelper#endCommitted and trace how global_table persistence is handled after globalSession.changeStatus(Committed) and globalSession.end(). Reproduce or inspect recovery after an abnormal seata-server termination, then verify that the affected committed global transaction can be cleaned up without affecting transaction consistency.
