    Use LinkedHashMap for deterministic WSDL namespace prefix assignment (#2944)
    
    ServiceWSDLBuilder uses a HashMap for the ns2prefix map, which causes
    non-deterministic namespace prefix assignment in generated WSDL. This
    leads to inconsistent output where elements may appear with or without
    namespace prefixes (e.g., <service> vs <wsdl:service>) depending on
    HashMap iteration order.
    
    Switch to LinkedHashMap to ensure insertion-order iteration, making
    the prefix assignment in getNewPrefix() deterministic.
