Fact-Checks Filters : Fetch Dynamic Content from Superdesk
The Region, Language, and Topic filters on the All Fact Checks page are not pulling content dynamically from Superdesk. The filter options need to be fetched from Superdesk via Publisher, and selecting a filter needs to return only articles matching that selection.

Acceptance Criteria

1. Region, Language, and Topic options are fetched dynamically from Superdesk, not hardcoded.
2. Selecting any filter returns only articles matching that selection.
3. Multiple filters can be applied together and results update correctly.
4. Adding a new language, region, or topic in Superdesk automatically appears in the filter with no code change needed.
5. If a filter returns no results, a clear message is shown to the reader.
6. All filters are tested in staging with real articles before go-live.
