fix(order): 解决移动端弹窗因 CSS display !important 导致 Vue v-show 隐藏失效无法关闭问题

- 根因定位：.mobile-popup-form 设置了 display: flex !important，该样式在 CSS 特异性中强于 Vue v-show 生成的行内 style="display: none;"；当弹窗点击关闭后，Vue 将变量置为 false 并完成退场动画，但由于样式强制 flex，弹窗退场后立刻以 flex 状态重新暴露在屏幕上（即“又弹出一个”），且由于此时 Vue 响应式状态已是 false，再次点击关闭按钮不会触发状态改变（即“第二次无法关闭”）
- 解耦容器与弹窗：移除 .mobile-popup-form 根节点上的 display: flex !important 与 overflow 强覆盖，弹窗内部增加 .popup-inner 容器承载垂直 flex 列布局与吸顶/吸底/滚动分区
- 严格验证：运行全量检查 ./scripts/check.sh，Go测试、MySQL测试、TypeScript检查及Vite生产构建 100% 通过
