Description

### Search before asking

- [x] I searched in the [issues](https://github.com/apache/iotdb/issues) and found nothing similar.

### Version

os:rocky linux 10.0
iotdb:apach-iotdb v2.0.4
C#程序集:Apach.IoTDB 2.0.2

### Describe the bug and provide the minimal reproduce step

string sql=select * from root.edge.device where time>2025-09-25 17:33:10.555 order by time asc limit 128;
using var dataSet=await sessionPool.ExecuteQueryStatementAsync(sql,5000);
返回的数据中,存在时间戳小于2025-09-25 17:33:10.555的数据。
dataSet.next()读取行,多行中的数据没有按照时间排序,存在时间乱序现象

### What did you expect to see?

按照条件返回正确数据

Research direction

Start by reproducing the SQL query under server memory pressure through sessionPool.ExecuteQueryStatementAsync, then inspect how rows are consumed with dataSet.next(). Verify that filtering excludes timestamps at or below 2025-09-25 17:33:10.555 and that results are ordered ascending by time; the issue is done when both conditions hold.
