feat(filters, recursive-routes): enhance configuration history and live data handling

- Introduced configuration history management in Filters and Recursive Routes pages, allowing users to view and restore previous configurations.
- Updated state management to handle live data loading and error states more effectively, improving user experience during data fetching.
- Added new components for displaying configuration history and integrated them into existing pages.
- Enhanced API interactions to support fetching and applying configuration revisions, ensuring data consistency across the application.
- Updated tests to cover new functionalities and ensure reliability.
