chore(test): E2E test-tabs-prevent-native-selection

[LKuchno]

Description

Adds an automated E2E test suite for the preventNativeSelection prop on TabsScreen, covering iPhone, Android phone, and the iOS More tab controller. Not covering iPad specific steps due to Detox limitations.

Closes: https://github.com/software-mansion/react-native-screens-labs/issues/1163

Changes

e2e/single-feature-tests/tabs/test-tabs-prevent-native-selection.e2e.ts

• New Detox test suite with 6 it blocks covering most of manual scenario - without step 19 and iPad specific scenario

test-tabs-prevent-native-selection/index.tsx
Added testID to the container view, screen name label, prevention state label, and toggle button. Added testID to all six "Select X" navigation buttons. Added tabBarItemTestID to all six route configs so tab bar items are directly addressable by Detox.

test-tabs-prevent-native-selection/scenario.md
Updated E2E status from "ongoing research" to "partially automated" with notes on what is not automated (iPad resize interactions, repeated More tab re-selection). Corrected steps 9–11 in the "Multiple tabs" section - step 9 now explicitly navigates to the Fourth tab and toggles prevention there before tapping Third, matching actual test behavior. Renumbered all subsequent steps accordingly.

Android tests are failing because toasts and the Tabs screen list are displayed 'under' the system navigation bar on older Android versions. This test is waiting for a fix or a workaround.
