Support price from wikidata

### Problem to solve

price (P2284) from wikidata is currently not supported but relevant for the community contribution score.

### Proposal

Add P2284 to the query and read the value out on transform.

For the score check:

business model
- in-app purchases
- in-app advertisements
- freemium

Start in /actions/lib/crawler/wikidata.ts and trace how Wikidata properties are added to the query and read during transformation. Add support for price (P2284), then verify that the transformed value is available for the community contribution score, including the business-model cases listed in the issue.
