pan 1d4769b080 feat(ui): 新增英雄长按详情弹窗功能
1. 拆分HeroBoxComp的次级属性与技能描述到独立弹窗HeroMoreCom
2. 新增UIID.HeroMore配置与对应预制体资源
3. 实现英雄盒长按0.5秒触发详情弹窗,点击任意位置关闭
4. 弹窗支持实时刷新受buff影响的英雄属性

* 1. 同步显示一个已登场英雄的基础信息(图标 / 名称 / 等级 / AP / HP
* 2. 长按英雄盒弹出信息面板UIID.HeroMore → more.prefab展示次级属性与技能描述。
* 3. 由 MissionCardComp 实例化到 herosBoxNode 下,最多 3 个,与场上英雄一一对应。
* 4. 英雄卖出 / 死亡后槽位保留,通过 applyEmpty() 显示为空英雄信息。
