Adopt kessai's authorize/capture lifecycle; settle the checkout and authorize the deposit for free bookings

Follow-up to kessai issue 3609923 and orchestra issue 3609941: adopts the renamed kessai payment lifecycle and adds a settle step to the booking workflow so a reserve-first checkout is captured off the request path.

• The yoyaku_booking example workflow gains a Settle payment (kessai_settle) node after Payment received: it captures the authorized checkout, retrying the transient gateway race, and a permanently declined capture routes back to the payment step so the booker can pay again. A Confirming your payment message shows while the capture settles.
• The deposit and no-show actions and the default settlement subscriber adopt the renamed kessai methods (authorize, capture, cancel), states (authorized, captured, cancelled) and the deposit record kind.
• refundablePayments now matches captured payments (the single money-taken state), so a cancellation refunds a captured checkout.

Includes an end-to-end test of the authorize then settle then capture path, and updates the French translation. Kernel tests are green.
