Adjust the availability of lender address fields in the transaction form.

Remove Billing Notes from the Transaction view in the Client. Dev believes this is an artifact from before lending billing was split into 2 parts and we have been unable to populate it with data.

Add LibBillingMethod as an option for addition to the layout. It's available in the LenderAddress record view, but not the transaction form view.

Rename the "Billing Groups" label in the Transaction form's Library tab. These are just groups and should not be described as specifically related to billing.
