feat(miniapp): align UI with H5 and harden device debugging

五个页面按 h5/css 的 style.css → ui-20261009 → ui-20261012 覆盖顺序逐条重排，
换算规则固定为 calc(N * var(--u)) → 2N rpx，固定 px 的字号保持 px。

- app.acss：换回 H5 设计 token（方角小倒角按钮 10rpx、卡片 14rpx、.chev 折线箭头）
- splash/profile/history：底图与按钮文字图改用 H5 资源，隐私/政策弹窗按 H5 重排
- report：环形分用 conic-gradient、人脸裁切窗口叠加 face_maps、标记点百分比盒、
  侧脸皱纹 pending/unavailable 文案；用 Playwright 抓 H5 94 个选择器几何比对，
  整页高 2438.7 vs 2438.67
- camera：淘宝 <camera> 组件在真机整页崩溃（嵌了微信专有的 <cover-view>），
  改为默认系统相机 + `config.nativeCamera` 开关 + pages/camtest 冒烟页验证组件
- permissions：淘宝用带前缀的 scope.camera（裸名返回 5022 Scope:camera信息不存在），
  先试带前缀再退回裸名，拒绝后不再重复弹窗
- voice：非 HTTPS 资源导致的异常不再冒泡成整页崩溃；app.js 加开发版错误 toast
- 开发版入口：权限诊断（启动页/相机页）、相机组件测试
- 测试 20/20（新增权限与相机能力用例）
