chore(splash): use app logo on icon background for native + flutter splash

Replace splash_chat_hebat with assets/icons/logo.png on @color/ic_launcher_background (customer #FF699F pink, mitra #FFFFFF white) across launch_background.xml (x2) and values-v31/styles.xml in both apps; copy logo.png into res/drawable. The mitra Flutter /splash screen still showed the old image — repoint it to assets/icons/logo.png (add assets/icons/ to mitra pubspec), keeping the route (it is the auth-loading gate). Native + flutter splash now match the launcher icon. Old splash_chat_hebat.png left in place but unused.
