feat(FalukantService, OverviewView): enhance church office information retrieval and UI display

- Refactored the `getHighestChurchOfficeInfo` method to utilize a new approach for retrieving the highest church office, improving accuracy and performance.
- Updated the `OverviewView` to format and display the highest political and church office names instead of raw rank values, enhancing user experience and clarity.
- Introduced a new method `formatCertificateHighestOffice` for better localization and presentation of office titles in the UI.
