Description

This PR introduces E2E Detox automation for the test-tabs-more-navigation-controller scenario, verifying the native iOS More navigation controller behavior.

Changes

test-tabs-tab-bar-more-navigation-controller.e2e.ts:

• Implemented Detox test suite covering baseline tab bar state, More tab navigation, programmatic tab selection, and repeated More tab tap behavior.
• Added dedicated repeated More tab selection test case verifying that onMoreTabSelected fires only on the first tap that opens the More list, not on subsequent taps.

test-tabs-more-navigation-controller/index.tsx:

• Added tabBarItemTestID props to all six tab route configs to enable tab bar item identification in tests.
• Added testID to the content view Text component and the navigation buttons View for reliable element targeting.

test-tabs-more-navigation-controller/scenario.md:

• Documents E2E automation coverage and known limitations (More tab selection/focused check in tab bar omitted due to Detox limitations; iPad steps not automated due to resize constraints).
