      Every wallet:send is now user-confirmed. A newly created wallet:send transaction is returned as
      pending_user_confirmation and only dispatched after the user confirms a one-time code via
      POST /transactions/{transactionId}/2fa. Users with 2FA configured receive the code on their own
      channel (SMS, WhatsApp, authenticator app); users with none are emailed the code.
