This does NOT use a Django model linked to a Django form. Just a simple Django form.
You will find the Django documentation on forms very confusing,
as it covers many very different things we do not need. This is simpler,
or at least, it is all in one place and you can see what it does, inctead of using invisible
Django defaults that a newcomer can't find.
(See also view/uploads.py for other simpler forms, as opposed to core/forms.py
which contains a couple of Django class-based forms.)
This subsumes much of the code which was in the pre-2022 non-troggle wallets.py script
and so this function is very long indeed and needs refactoring.
Much of the logic used here lives in the Class functions for Wallet.
