Subject: [PATCH] fix(android): give launch splash a day/night background

The Android 12+ system splash drew the launcher icon on the launch
theme's colorBackground, which is white because AppTheme inherits the
static Theme.AppCompat.Light.* family (not DayNight). The loading icon
therefore showed a white background even in dark mode.

Set android:windowSplashScreenBackground to @color/windowBackground,
which has a values-night variant (#131314), so the splash tracks system
day/night and matches the WebView surface painted by WebHelper.
