[Bug] Paimon Native Scanner returns FORBIDDEN (403) on specific tables when using private S3-compatible storage, JNI scanner works fine

### Search before asking

- [x] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues.

### Version

doris-4.0.5

### What's Wrong?

When querying Paimon tables via an External Catalog backed by a private S3-compatible storage, some tables consistently return AccessDenied / FORBIDDEN when read by the Paimon Native Scanner. Switching to the JNI scanner resolves the issue immediately.

The problem is table-specific within the same catalog and schema: tables pay_manager, relation, term succeed with native scanner, while ods_pxf_db_cm_contract_pay_info_fd always fails.
