\`Email Didit's standard due-diligence questionnaire to a Travel Rule counterparty VASP.

Endpoint:
POST https://verification.didit.me/v3/travel-rule/vasps/{vasp_id}/questionnaires/

Authentication:
Use the x-api-key header with my Didit API key.

Example call:
curl -X POST "https://verification.didit.me/v3/travel-rule/vasps/{vasp_id}/questionnaires/" \
-H "x-api-key: YOUR_API_KEY" -H "Content-Type: application/json" \
-d '{"sent_to": "travelrule@counterparty.example"}'

Body (optional):
\- sent_to - a compliance address on record for the counterparty: for a directory entry its compliance address or a contact my application sees (GET /v3/travel-rule/vasps/{vasp_id}/ lists contacts), for a Didit network member its confirmed compliance email. Default: the address a Travel Rule email to the counterparty goes to (my own contact first, then a platform contact, then the entry's compliance address). Any other address is refused.

What happens:
\- 202 with the questionnaire {id, status: "SENT", form_version, sent_to, sent_at, expires_at, ...}. The email carries a single-use link to a page where the counterparty answers every question of Didit's standard questionnaire.
\- The counterparty has 30 days (expires_at); after that the link stops working and the questionnaire is EXPIRED.
\- Once answered, the status is ANSWERED and the answers stay current for 365 days (valid_until). Read them with GET /v3/travel-rule/vasps/{vasp_id}/questionnaires/.
\- A new send replaces my earlier unanswered questionnaire to the same counterparty: that one becomes EXPIRED and its link stops working.
\- The questionnaire and its answers are private to my application.

Failure modes:
\- 400 - sent_to is not a valid email or not a compliance address on record, or the counterparty has no compliance address on record yet.
\- 404 - no directory entry or listed Didit network member has this id, or the id is my own VASP profile.
\- 429 - a questionnaire went to this address less than a minute ago.
\- 503 - the email could not be sent and no questionnaire was created; try again.
