1. 调整近战默认攻击距离从150改为100 2. 将击退相关属性从概率改为击退距离增量，同步更新所有配置、UI显示和技能描述 3. 移除旧的击退概率判定逻辑，改为直接应用击退距离增量 4. 优化受击击退的处理流程，统一参数传递

/**
|
||
* @file MoveComp.ts
|
||
* @description 统一移动组件与系统（英雄 + 怪物）
|
||
*
|
||
* 核心规则：
|
||
* 1. 准备阶段：双方原地待命，不推进不索敌。
|
||
* 2. 战斗阶段：双方向最近敌人推进，进入攻击范围（model.dis）后停止移动并攻击。
|
||
* 3. 场上无敌人：停止移动（战斗结束，由 MissionComp 进入结算）。
|
||
* 4. 击退/位移不会把单位推出屏幕：HERO 不越过 BoxSet.LETF_END，MON 不越过 BoxSet.RIGHT_END。
|
||
* 5. 推进方向无上限限制，直到接触敌人或抵达敌方边界。
