EnergyGift appears as the gift property on an EnergyTradeOffer.
A prosumer publishes an offer with gift set; the offer is listed at price 0. The intended recipient
discovers the offer by hashing their phone number and matching it to lookupHash. They claim
the gift by presenting the shared secret (pre-image of claimVerifier) in the select message.
