Add AS400 Data Queue assets from a PCML file in the Designer

A module that uses the AS400 Data Queue connector now has an Add Asset button. Previously the assets page for such a module offered nothing and told you to use the OL-Integration CLI instead. Choose With a PCML source file, upload the PCML that describes the message layout, and the asset is created in the module. The asset name is filled in from the file you upload and can be changed before you add it.

Request and response record layouts can now come from two different files. Request PCML is required and describes the message written to the queue; Response PCML is optional and describes the message read back — supply it when the two layouts differ, which is the common case in a real data queue integration. Leaving it empty keeps the previous behaviour, where the response is built from the request file's own output fields. Queue names continue to come from the module's connection profile, and the connector now exposes key, inputQueue and outputQueue as runtime properties you can set per invoke step. Fetching a PCML from a path on disk remains a CLI-only option.
