/**
 * @file EquipListComp.ts
 * @description 装备商店单个装备项组件（UI 视图层 + 购买逻辑）
 *
 * 职责：
 *   1. 渲染单个装备卡的显示信息（名称、等级、属性词条、图标）。
 *   2. 处理购买点击 → 扣费 → 派发 UseSkillCard 事件触发装备生效。
 *
 * 装备使用机制：
 *   与技能卡使用流程一致——购买后派发 GameEvent.UseSkillCard，
 *   由 MissSkillsComp 接收并创建 SkillBoxComp 实体，
 *   SkillBoxComp 按 Field 类型被动驻场，属性加成由 FieldSkillHelper 全局聚合。
