Allow manual stripe payment
Usage has shown that it may be required to be able to do manual stripe payment.
Example: if the initial invoice for which a payment was done is wrong, the corrected invoice will have to be paid but it is a manual operation so sale_payment does not exist etc.
So I propose to show the stripe_customer and/or stripe_token, there are not so much sensitive (because they can be used only for one stripe account) to get access from the account payment group.
