[Bug] IndexOutOfBoundsException when lookup join sql

### Search before asking

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

### Paimon version

paimon 1.1.1 +flink 1.18
Basically, all the trigger conditions are met:
1. DEBUG logging was enabled for org.apache.paimon.flink.lookup.FileStoreLookupFunction in the production environment.
2. A lookup join is being used, and the table created is a SecondaryIndexLookupTable.
3. The join key is contract_no, which is not the complete primary key. The logs show _KEY_contract_no and _KEY_reg_valid, indicating that the full key also involves reg_valid.
4. There is a mismatch in the field order among the lookup projection, Paimon's internal read schema, and the original table schema.
5. The DEBUG branch attempts to print the matched rows, which leads to the execution of logRow().

LookupJoin[8] switched from RUNNING to FAILED

### Compute Engine

flink 1.18

### Minimal reproduce step

1. DEBUG logging was enabled for org.apache.paimon.flink.lookup.FileStoreLookupFunction in the production environment.
2. A lookup join is being used, and the table created is a SecondaryIndexLookupTable.
3. The join key is contract_no, which is not the complete primary key. The logs show _KEY_contract_no and _KEY_reg_valid, indicating that the full key also involves reg_valid.
4. There is a mismatch in the field order among the lookup projection, Paimon's internal read schema, and the original table schema.
5. The DEBUG branch attempts to print the matched rows, which leads to the execution of logRow().

### What doesn't meet your expectations?

none

### Anything else?

_No response_

### Are you willing to submit a PR?

FileStoreLookupFunction.lookup から開始し、logRow() を呼び出す DEBUG ロギングパスまで lookupInternal をたどります。SecondaryIndexLookupTable に対する Flink 1.18 の lookup join、部分的な contract_no キー、DEBUG ロギングを有効にした状態で問題を再現します。一致した行をロギングしているときに lookup が IndexOutOfBoundsException で失敗しなくなれば完了です。
