handleAppResumedForTest method
Test-only seam (BEH-12, additive): drive the guarded resume re-probe
(_handleAppResumedNetworkReprobe) directly. The production wiring in
_initializeLifecycleService runs only after getInitialData (Firebase-
coupled); this seam exercises the hook's guards (loading gate, kill-switch,
epoch/close fencing, resume-recovery resync) in isolation.
Implementation
@visibleForTesting
Future<void> handleAppResumedForTest() => _handleAppResumedNetworkReprobe();
