refactor(login): 使用 wd-form 官方表单校验替换手动校验，优化错误提示展示方式

- 使用 wd-form + wd-form-item 配合 formSchema 实现表单校验
- 校验错误改为内联提示(error-type=message)，不再弹窗
- 修复 wd-form-item 水平布局导致错误提示与输入框挤在一起的样式问题
- 为 wd-form-item 添加 layout=vertical 并将错误提示强制显示在输入框下方
- 移除 manifest.json 中不兼容小程序编译的 darkMode/themeLocation 配置
- 移除 pages.json 中小程序不支持的 animationType/animationDuration/customize/overlay 字段
