Looks up the TXT record through DNS over HTTPS and marks the domain verified when it matches.

`POST /orgs/{org}/sso/domains/{domain}/verify`

## TL;DR

| Question | Answer |
|---|---|
| What does it do? | Check a domain's DNS record. |
| What does it take? | `org`, `domain` in the path. |
| What does it return? | Status 200 with a body of type [`SsoDomainVerify`](https://docs.plotwork.dev/api/schemas.md#ssodomainverify). |
| What can go wrong? | `401` not signed in; `403` a member or a reader (orgs.forbidden), a plan without single sign-on (plan.sso_not_included), or the request came from an origin that may not make changes; `404` no such organisation, or the caller is not a member of it; `409` another organisation verified this domain (sso.domain_taken); `429` too many requests; `503` single sign-on is not set up on this server (sso.unavailable), or organisations are not. Every failure uses the one error envelope. |

## What it does
