fix: footer ignoring safe area bottom inset

iOS: Pin footer bottom constraint to safeAreaLayoutGuide.bottomAnchor so
content doesn't render behind the home indicator on notched devices.
When the keyboard is visible its height already includes the safe area
inset, so no double-compensation is needed.

Android: Subtract bottomInset in positionFooter so footer content doesn't
render behind the navigation/gesture bar. When the keyboard is visible,
currentKeyboardInset already accounts for the bottom inset.
