💄 style(verify-code): 调整 APP 端验证码输入框的隐藏方案

- 将原生输入框移出可视区域，避免 Android 设备上原生光标与自绘数字冲突
- 为 xt__verify-code 增加 overflow 隐藏，输入内容与光标不再显示在验证码格上

♻️ refactor(login): 移除 u-code 组件并自实现验证码倒计时

- 用 displayCodeTip 计算属性配合计时器替换 u-code，统一验证码按钮文案展示
- 新增 onBeforeUnmount 清理倒计时定时器，避免内存泄漏
- 重构 fetchCode 发送逻辑，简化校验与错误处理分支
- 更新获取验证码按钮样式为橙色渐变并调整文字颜色

♻️ refactor(live): 为 APP 端补充直播服务占位实现

- 通过条件编译在 APP-PLUS 下提供 LiveChatService 与 LiveMqttService 空实现
- 避免 APP 端引入直播聊天与 MQTT 依赖，仅保留其他平台原有逻辑
