Fix in news, first android notification service

- Introduced `retryOnNetworkFailure` function to handle network-related exceptions and retry requests.
- Updated `GalleryRepository`, `HomeRepository`, `LoginRepository`, `MannschaftenRepository`, `NewsletterRepository`, `PasskeyRepository`, `ProfileRepository`, `PublicPagesRepository`, `SpielplanRepository`, `TermineRepository`, and `TrainingRepository` to use the new retry mechanism.
- Added `ConnectivityMonitor` to track internet connectivity status and notify UI components.
- Enhanced `NavigationViewModel`, `CmsViewModel`, `MembersViewModel`, and `MemberAreaViewModel` to reload data when connectivity is restored.
- Bumped app version to 0.9.16.
