Beneficiaries
Archive a Beneficiary
Removes a Beneficiary from the address book: it stops appearing in GET /v1/beneficiaries and the CSV export, new Payouts to it are refused with BENEFICIARY_ARCHIVED, and every live collection link is cancelled. Nothing is deleted — GET /v1/beneficiaries/{id} still resolves it with archived_at set so a Payout’s payee stays lookup-able, Payouts already in flight still disburse, and the compliance evidence is retained. The email address is freed, so the same payee can be registered again. Idempotent: re-archiving is a success no-op.
