fifa17-recon: fix store transaction wrongly auto-opening packs

store/transaction receives {"state":"TRANSACTIONCANCEL"} (cancel/close)
and {"packId":N} (pack-details fetch on store load) -- neither is a
confirmed purchase. The handler treated packId as a buy and even
defaulted to opening a Gold Pack on cancels, silently spending coins.

Make store_buy a safe no-op that logs every body, so the real
purchase-CONFIRM signal can be identified from a deliberate in-game buy
and open_pack() gated on exactly that. Save restored on next fresh run.
