Description
### Search before asking
- [x] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar.
### Paimon version
paimon 1.0.1
### Compute Engine
flink 1.18
### Minimal reproduce step
i have a dedicated compaction with consumer_id, but sometimes i still have error "org.apache.paimon.table.source.OutOfRangeException: The snapshot with id 2144 has expired. You can: 1. increase the snapshot or changelog expiration time. 2. use consumer-id to ensure that unconsumed snapshots will not be expired.
at org.apache.paimon.utils.NextSnapshotFetcher.getNextSnapshot(NextSnapshotFetcher.java:68) ~[flink-catalog-connector-paimon-3.2.0-SNAPSHOT.jar:?]
at org.apache.paimon.table.source.DataTableStreamScan.nextPlan(DataTableStreamScan.java:184) ~[flink-catalog-connector-paimon-3.2.0-SNAPSHOT.jar:?]"
and i see the value of consumer in hdfs file is
"{
"nextSnapshot" : 2931
}"
### What doesn't meet your expectations?
the consumer-id read snapshot is 2931, which means consumer has read all the snapshots that are less than 2931, but i still have error "The snapshot with id 2144 has expired."
### Anything else?
_No response_

Research direction
Start with org.apache.paimon.utils.NextSnapshotFetcher.getNextSnapshot at NextSnapshotFetcher.java:68 and DataTableStreamScan.nextPlan at DataTableStreamScan.java:184. Reproduce the expired snapshot error on Paimon 1.0.1 with Flink 1.18 and inspect the HDFS consumer file containing nextSnapshot 2931. Done means explaining why snapshot 2144 can expire despite that consumer value and correcting the behavior.
