refactor: pipeline SPARQL and wiki data in parallel

- Merge fetchWikiArticles + fetchWikiArticlesData into one pipeline
- SPARQL producer fetches batches, commits each to DB, forwards resolved articles
- Wiki data consumer runs concurrently, fetching at 2s/request
- Each SPARQL batch commits independently (no global transaction)
- Rate limits respected for both Wikidata SPARQL and wiki server
- No parallel requests to either endpoint
