shopify_draft_proxy/proxy/gift_cards

Mirrors src/proxy/gift-cards.ts.

Pass 19 ships the four query roots (giftCard, giftCards, giftCardsCount, giftCardConfiguration) plus the seven mutation roots (giftCardCreate/Update/Credit/Debit/Deactivate, giftCardSendNotificationToCustomer/Recipient).

Gift cards never delete — giftCardDeactivate flips an enabled flag and stamps deactivated_at instead. The store therefore tracks gift_cards + gift_card_order only (no deleted-id set) and stage_create_gift_card doubles as stageUpdateGiftCard.

Currency / decimal formatting follows the TS handler’s formatDecimalAmount exactly: round to 2dp, then trim a single trailing zero, but never below <int>.0. Negative debit amounts on transactions are signed by the handler — the underlying balance math uses unsigned magnitudes.
