Can you just modify RESTTokenFileIO? RESTUtil.merge should be a very simple method, just updates merge into targets.

Purpose
When using Paimon with DLF (Data Lake Formation) server, the server passes default OSS endpoint values (e.g., fs.oss.endpoint=oss-cn-hangzhou-internal.aliyuncs.com) through tokens. However, these default internal endpoints are not accessible in all client environments, causing connectivity issues. The client-provided options should take precedence over server defaults, but the previous merge logic didn't handle this correctly. This PR introduced DLF_OSS_ENDPOINT configuration option in RESTCatalogOptions to allow clients to specify their preferred OSS endpoint.
