tools/server: shop-item-time patch — NPC shop items carry a new item's time sockets

40250 game zeroes alSockets for NPC (shop.cpp) and extended (shopEx.cpp) shop items, so
uitooltip shows 'remaining 0 min' for mounts and item-mall time items. MT_GetNewItemSockets
fills them with ITEM_MANAGER::CreateItem's rules (UNIQUE remain time, auto potions,
LIMIT_REAL_TIME, LIMIT_TIMER_BASED_ON_WEAR). Deployed on 203; mount shop 20368 verified.
