The logic to fetch member for a checkout session was incorrectly creating a new customer instead of finding an existing one, so the member's billing details was not getting updated.

This refactors the members-api module so that it is easier to test going forward,
as well as easier to understand & navigate. The Stripe API no longer contains
storage code, this is all handled via the member repository. And we have dedicated
services for webhooks, and stripe plans initialisation.
