Submit Sell Payout (Phase 2b)

Phase 2 of the two-phase off-ramp (sell) flow. Submit the customer's beneficiary details to trigger the fiat payout. The system obtains an FX quote (if cross-currency), maps the beneficiary fields to the payout provider, and initiates the bank transfer.

On success, the ramp intent automatically transitions to completed.
