Service price overrides in PaymentModal were only used for frontend
calculations but not persisted to the backend. This caused receipts
and subsequent payments to use original prices instead of overridden
ones.
Added saveServiceOverrides() function that calls PUT
/api/admin/bookings/{id}/services before payment to persist any
price changes. Called in both handleCardPayment and
handleSavedCardPayment before applyLoyaltyRedemption().
