fix: clear stale APPROVED state when online version is older than submitted

- Add AppStoreService.clearStoreReview() to remove a store's review entry
  from storeReviewStatus JSON (used for false-positive cleanup)
- refreshStoreReviewStatus: when existing state is APPROVED but polled
  onlineVersionCode < submittedCode, clear the stale state instead of
  leaving the misleading nonCurrentRelease flag in place
