WCPOS StoreApps Smart Coupons

It intentionally uses the wcpos-storeapps-smart-coupons slug because other plugins also use “Smart Coupons” naming. Current compatibility layer: - applies store-credit (gift card) coupons to order totals at the WCPOS checkout by reporting a REST context while an unpaid POS order with a smartcoupon recalculates totals, so StoreApps' own order-discount logic runs (its gates otherwise only open for admin order edits, REST requests, and store-api orders); - prunes stale smartcouponscontribution entries when a store-credit coupon is removed at the POS checkout, so removed gift cards are not deducted on payment; - captures smartcouponscontribution order meta for POS REST orders so StoreApps can deduct the correct partial store-credit amount from gift-card balances; - adds a private order note after StoreApps processes the POS store-credit redemption so staff have an audit trail of the coupon code, amount used, and current balance; - appends the remaining store-credit balance to the existing coupon des
