use xmlrpc to load pets, not json.php

The AMFPHP gateway's json.php endpoint has always had a problem parsing pets whose names start with digits… I've dug into it before, and checked again today, and there really is just no way around it: d584b58e95/core/json/app/Actions.php (L43)

And there aren't any reliable AMFPHP Node libraries out there to make the actual native AMF call.

Buuuut! In today's investigation, I noticed the xmlrpc.php endpoint for the first time. And, wouldn't you know it, there's //great// reliability for something as enterprise-standard as that!

So here, I've switched over to using an xmlrpc client library, which simplifies our calling code //and// makes number pets work correctly 😁 I wouldn't have done it just for the simplification, I think bringing in a library is net more complexity… but getting this finally right is a big relief.
