Builds and broadcasts a user->external-address PSBT with change back to the user's own address, fee deducted from the withdrawn amount, and registers the confirmation handler that marks the withdrawal confirmed. Shares the per-user lock with bets so a build never races a spend from the same UTXO set. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
