背包扩展到 5 页：服务端补丁 + DB 迁移 + 客户端 mt_inventory

- GameType.h: c_Inventory_Page_Count 2 -> 5; SQuickSlot.Position BYTE -> WORD
- quickslot 包/接口 pos 改为 WORD（CG/GC 5 字节），wire_classic 同步
- mt_inventory PORT 模块：inventorywindow.py 装备格 90 -> EQUIPMENT_SLOT_START 重映射、5 个小页签、
  自动药水高亮与 SelectItemWindow 扫描全部 5 页；40250 脚本保持不变
- tools/server/inventory-5-pages: server.patch（格子布局 +135、quickslot WORD）、migrate_db.py、README
