/**
 * @file ItemListComp.ts
 * @description 商店列表项组件（UI 视图层 + 购买逻辑）
 *
 * 职责：
 *   1. 渲染单个商品/装备卡的显示信息（名称、等级、属性词条、图标）。
 *   2. 处理购买点击 → 扣费 → 根据卡牌类型派发对应事件触发购买效果。
 *
 * 支持类型：
 *   - 装备卡（trigger_type=Field）→ 派发 UseEquipCard，由 MissEquipComp 处理。
 *   - 商品/药品卡（kind=Potion）→ 派发 UseItemCard，由 MissSkillsComp 处理（一次性 buff）。
 *
 * 设计说明：
 *   本组件同时服务于装备商店和商品商店，通过 cardData 的 trigger_type / kind 自动判断类型。
