Top up a Steam account wallet, paid from your Waxpeer balance

Debits amount from your Waxpeer balance and credits the Steam account after fees (give_amount). Passing the same custom_id twice returns the existing top-up instead of creating a second one, so retries are safe. Poll GET /v1/steam-topup for the final status: canceled means the money was returned to your balance.
