Set up the MassPay wallet

Set up the account's MassPay payout wallet from the same profile the dashboard's setup form collects, and make it the default payout method.

Required: firstName, lastName, email, country, address1, city, stateProvince, postalCode, plus businessName when accountType is BUSINESS. Optional: middleName, mobileNumber, language, dateOfBirth, address2. Enter everything as on the payee's government-issued ID. Every field is checked before anything is sent to MassPay; a refused profile answers 400 invalid_profile naming the first bad field, with all of them in errors.

• No payee yet → the payee is created at MassPay with the full profile (201).
• Payee exists but lacks required details (see missingFields on GET /payouts/masspay/profile) → the fields you send fill them in. country, email and businessName stay as MassPay has them; send at least the missing fields.
• Payee complete → the body is not needed; the wallet is (re)attached.

Activation: before the first payout to the wallet, the payee must open activationUrl once in a browser (a MassPay requirement). The link expires — get a fresh one from GET /payouts/masspay/activation when you send the payee there. Payout requests to a wallet that is not activated are refused (masspay_not_activated).

Safe to retry: there is one MassPay payee and one wallet per account. The key's own account only, after the ID check.
