Subject: [PATCH] fix(test): keep the typewriter contract on its own component

The home-surface join pulled the onboarding shell's aria-busy into the typewriter slice. The typewriter file itself still announces the finished line once.

 - 触发条件：首页拆分把引导屏 JSX 从 `page.tsx` 搬到 `home-onboarding-shell.tsx` 后推 staging。
 - 根因：合同把 `<BirthTimeRectification` 锁在旧的首页文件清单里。拆分后组件还在，清单没跟上。
 - 修复：扫描面加入 `home-onboarding-shell.tsx`，并要求 `page.tsx` 仍挂载 `<HomeOnboardingShell`。其余断言不放宽。

 - 防复发：引导屏再搬家时，合同必须同时锁住挂载点和组件文件，不能只扫 `page.tsx`。
