+Subject: feat(trino): Expose Iceberg REST client proxy settings
+
+The Iceberg REST client (HTTPClient) already supports proxy settings via
+rest.client.proxy.hostname, .port, .username and .password, but Trino's
+REST catalog has no way to set them.
+
+Add iceberg.rest-catalog.http-proxy, .http-proxy.username and
+.http-proxy.password and pass them through to those client properties.
+Nothing changes unless the new options are set.
