[FIX] website_quote: utility method to determine the transaction type of an order

The transaction `type` of an order can depend according
to the order.

For instance, if the order leads to recurring payments,
the transaction type became `form_save`
instead of `form`.

This new method allow to easily override this `type` value
for other modules, so the entire button
rendering code does not have to be
copy/pasted.
