fix(kiosk): force dark color-scheme so bundled AIUI renders its dark theme

Browse Source 
AIUI themes via @media (prefers-color-scheme) and falls back to its light
variant (white panels) when the browser reports no preference — which the
minimal kiosk X session does, so AIUI came up light instead of its designed
dark. The main UI hardcodes dark and is unaffected. Push two independent
dark signals on the kiosk Chromium: GTK_THEME=Adwaita:dark (version-
independent, can never force light) and --blink-settings=preferredColorScheme=0
(0 = kDark in modern Chromium). Needs on-device kiosk verification.
