#266 UK: Adding UK report - Payment Methods Report 

Report to find order balances. Search per ordercycle and select multiple payment method options. Working, but not complete to spec yet, as not searchable per delivery option.

Purpose of this report is so that on pickup/delivery hub can print a report for all, say, Cash On Delivery and Cheque on Delivery payment methods to ensure payment collection is easy.

There's a create_enterprise_user method in `support/request/authentication_workflow.rb`
