This PR adds a new `billing_customers` table to hold the billing customers. Previously we were storing both the `stripe_customer_id` and `stripe_subscription_id` in the `billable_subscriptions` table. However, this creates problems when we need to correlate subscription events back to the subscription record, as we don't know the user that the Stripe event corresponds to. By moving the `stripe_customer_id` to a separate table we can create the Stripe customer earlier in the flow—before we create the Stripe Checkout session—and associate that customer with a user. This way when we receive events down the line we can use the Stripe customer ID to correlate it back to the user. We're doing some destructive actions to the `billing_subscriptions` table, but this is fine, as we haven't started using them yet. Release Notes: - N/A
