Asks Stripe for the checkout session and its subscription and stores the same state the webhook stores.

`POST /user/billing/verify-checkout`

## TL;DR

| Question | Answer |
|---|---|
| What does it do? | Read a finished checkout back. |
| What does it take? | A JSON body of type [`VerifyCheckoutBody`](https://docs.plotwork.dev/api/schemas.md#verifycheckoutbody). |
| What does it return? | Status 200 with a body of type [`BillingState`](https://docs.plotwork.dev/api/schemas.md#billingstate). |
| What can go wrong? | `400` the body is not valid; `401` not signed in; `403` the request came from an origin that may not make changes; `404` no such checkout session for this account; `429` too many requests; `502` stripe could not complete the request; `503` billing is not set up on this server. Every failure uses the one error envelope. |

| Field | Type | Required | Description |
