refactor(campaign): delegate gift-reward-type check to GiftRewardTypes

Delete local IsSupportedGiftRewardType and replace its single call site with
GiftRewardTypes.IsSupported — Card (5) and Sleeve (6) are now accepted.
Update unsupported-type test sentinel from 5 (Card) to 11 (SpotCard).
Add Card and Sleeve success-path tests; full suite 1152/1152.
