<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Changes only Android instrumentation test utilities; no production app
behavior.
> 
> **Overview**
> Centralizes Espresso handling for the **home screen widget promo**
bottom sheet so instrumentation tests are less flaky on fresh installs.
> 
> The dismissal logic moves from a private helper in `BasicJourneyTest`
into shared **`dismissWidgetPromoIfPresent()`** in `EspressoUtils.kt`
(with a short comment tying it to `CtaViewModel.canShowWidgetCta`).
**`preparationsForPrivacyTest()`** now calls that helper after the
browser menu is ready, so privacy tests get the same dialog cleanup as
the basic journey test.
