[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().

Comienza en FileStoreLookupFunction.lookup y sigue lookupInternal hasta la ruta de logging DEBUG que llama a logRow(). Reproduce el problema con un lookup join de Flink 1.18 sobre una SecondaryIndexLookupTable, una clave contract_no parcial y el logging DEBUG habilitado. La tarea estará terminada cuando el lookup ya no falle con IndexOutOfBoundsException al registrar las filas coincidentes.
