Moby von Briesen 149f6f2626 satellite/payments: Implement coupon codes
Full path: satellite/{payments,console},web/satellite

* Adds the ability to apply coupon codes from the billing page in the
satellite UI.
* Flag for coupon code UI is split into two flags - one for the billing
page and one for the signup page. This commit implements the first, but
not the second.
* Update the Stripe dependency to v72, which is necessary to
use Stripe's promo code functionality.
