feat(client): price server items with the 1.13c #10107/#10071 port
ItemData -> TransactionCostInput adapter (packet defense/durability/ quantity as base stats, properties and runeword stats as full stats, rare affix pairs, socket children). Code-only gamble previews (flag 0x02000000) are priced only for type 2. Capture checks: all 46 Charsi items price, every gamble preview costs > 2 gold (server answered result 12), repair-all with full durability costs 0.
