tech(useFocusVisible): refactor hook without AppRootContext

[EldarMuhamethanov]

• Unit-тесты
• Release notes

Описание

Рефакторинг механизма focus-visible с отвязкой от AppRootContext: трекинг keyboard перенесен в useKeyboardInputTracker, а useFocusVisible больше не зависит от AppRoot.
Также упрощен AppRootContext (удалено поле keyboardInput) и обновлены тесты, которые раньше эмулировали keyboard input через контекст.
