We'll want to re-use the PSBT funding functionality from the wallet kit sub server in the main RPC server. To be able to dynamically obtain an instance of the wallet kit server we need to know its name under which it registers itself in the list of sub server. We export the name so we don't have to hard code it in the main server.
