Add special page and API endpoint that show information from math Wikibase items
Add a special page and an API endpoint to fetch data from Wikibase items with a given qID. The special page summarizes information from Wikibase. The API endpoint allows to request the information directly. Both, the API endpoint and the special page, fetch the data from a new helper class for consistency.
