chore(android-terminal): drop deprecated Window.statusBarColor write

Window.setStatusBarColor was deprecated in API 35; the recommended path
is enableEdgeToEdge() (already called in MainActivity) which lets the
theme drive the color. Keep the isAppearanceLightStatusBars line so the
icon tint stays correct on the brief moments immersive mode reveals the
bars on swipe.

Silences the last Kotlin compile warning. Build is clean.
