Replaces the TODO_REAL_* ad-unit placeholders with the owner's real AdMob
console ids (publisher pub-5605900229781491) and the native AdMob app ids
(iOS ~8397095848, Android ~8257495040) in place of the Google sample ids.
Debug builds still serve Google test ads via kDebugMode; release builds now
use the real units.
