feat(frontend): #80模拟盘命名对齐实盘+#81批量删除+#82实盘预览名清空——#80:autoName改{实例名}_v{YYYYMMDD}{minor}同实例同日递增不分模式(原{实例名}·{模式}v{N}连排+英文模式段,用户定稿与实盘同格式);#81:模拟盘/实盘列表加多选列(仅非运行行可选=运行中先停止)+批量删除按钮(选中才显示带数量徽标,确认框列账户名前5,循环既有DELETE接口,N成功/M失败汇总+失败明细toast);#82:新建实盘初始name live-600000改空串,未选实例时预览显示占位「—（选实例后自动生成）」(原默认值顶掉占位提示),选实例后autoName生成,服务端兜底(#78)双保险;build绿(vue-tsc) [nas]
