## **Description**

A recent change to the settings pages broke a Snaps E2E test on main.
This PR fixes that by adding additional steps to exit the settings menu.

> [!NOTE]
> Fix Snaps E2E by adding back-navigation support and updating tests to
exit Settings before proceeding.
> 
> - **E2E Page Objects**:
>   - `e2e/pages/Settings/SnapSettingsView.ts`:
> - Add `backButton` getter using
`CommonSelectorsIDs.BACK_ARROW_BUTTON`.
>     - Add `tapBackButton()` to tap the back arrow.
> - **E2E Tests**:
>   - `e2e/specs/snaps/test-snap-management.spec.ts`:
> - After toggling Snap enablement, navigate out of Settings via two
`tapBackButton()` calls and `SettingsView.tapCloseButton()` before
continuing.
> - Ensure `SettingsView.tapSnaps()` is invoked where needed before
selecting a Snap.
