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.
flutterfire configure registered the iOS/Android apps under project
block-seasons and generated firebase_options.dart + native config. main()
now initializes Firebase and routes analytics through FirebaseAnalyticsBackend
in release builds (console logger in debug, so dev traffic never pollutes
GA4). Firebase init is guarded — failure falls back to the debug logger
rather than blocking startup.
firebase.json keeps the existing Hosting config and gains the FlutterFire
platform section. Client config files are committed (they ship in the binary;
Firebase security is enforced by rules, not config secrecy).
flutter analyze clean, all 161 tests green.

Pure advanceStreak (1-day grace none, milestone flags at 3/7/14/30),
persisted in the save blob; StreakNotifier advances on every finished
attempt; home screen flame chip and milestone snackbar. Fix flutter
create's camelCased iOS bundle id and underscored Android application
id to the agreed lowercase form before any store registration.
