Lakehouse Proxy Config Introduced (Breaking)

The Service resource now includes a new lakehouseProxyConfig field, referencing the newly introduced LakehouseProxyConfig schema. This configuration enables routing requests for migrated namespaces to a Lakehouse Iceberg REST Catalog during phased migrations. Both the lakehouseProxyConfig field on the Service resource and its nested properties, catalog and namespaces, are explicitly marked as readOnly. This means developers cannot set these values; they are output-only, managed by the Metastore service. Any client code attempting to write to these fields will now encounter a breaking change and fail, as they are strictly server-managed outputs.
