Issue #23459 Issue #23937 Support external pre-auths with no card_id.

Uses:
https://github.com/xtuple/qt-client/pull/381
Please use `E`. Those Paypal support stubs are commented out, so using `E` or `P` requires the same amount of work. `E` is safer since it doesn't raise the question of whether or not we support Paypal, at least on the Qt side.

People do map different card types to different accounts. That was a commonly-requested feature.

I'll modify the Qt configureCC to set the bank account and Cash Receipt window to display `E`xternal pre-auths if they appear.
