/**

 * 
 * 验证提现方式选择弹窗（account-type-select.vue）与提现主页（withdraw.vue）
 * “如果后台设置关闭的 这里隐藏掉 只有开启才显示” 业务规范自动化测试：
 * 
 * 1. 组件源码结构静态检查（filteredTypeList 仅渲染后台开启的提现渠道）
 * 2. 彻底废除旧的 disabled 灰色禁用行显示，改为未开启方式完全不渲染
 * 3. 提现主页面关闭渠道自愈与单渠道智能预选逻辑验证
 * 4. 各种后台配置场景模拟（单银行卡、微信+银行卡、全开、全关等）
 * 5. API 模拟测试（正常场景、业务拒绝场景、参数边界场景）
