fix(android): pass IME insets through to WebView for keyboard viewport resize

WindowInsetsCompat.CONSUMED was preventing the WebView from receiving
IME insets, causing visualViewport and innerHeight to not update when
the keyboard opens on Android.

Changed to only zero out systemBars/displayCutout (which we handle via
padding), while letting IME pass through so the WebView's built-in
adjustResize mechanism can properly resize the layout viewport.
