Summary
Email a 6-digit confirmation code to an external address. Body is {email, client_id?}. HTTP 202 while pending. HTTP 200 when the address is already verified, and no mail is sent. The code is not stored in a Cooper inbox and is not returned. The same client_id returns the original destination. At most 5 destinations (409 forwarding_limit). The inbox itself, an address at cooperemail.com, and any Cooper inbox are 400 forwarding_target_not_allowed. Limited to 5 emails per hour per IP and 3 per day per address (429 rate_limited). Write permission is inbox_update. Forwards later count toward the monthly send quota.

Idempotency
client_id makes this write idempotent. Sending the same client_id again returns the original object instead of creating a duplicate.
