fix(app): add aria-checked to Switch for E2E toBeChecked() assertions

React Native Web does not map accessibilityState.checked to aria-checked
for role="switch", so Playwright's toBeChecked() always finds the element
unchecked. Adding aria-checked={value} directly to the Pressable sets the
attribute explicitly.

Update the switch.test.tsx mock to accept and pass through the explicit
aria-checked prop, keeping the mock faithful to the fixed component.
