feat: fetch Wikipedia article titles via Wikidata SPARQL

- Query Wikidata SPARQL in batches of 30 for entries missing wiki_article
- Store wiki_article title in imdb table
- Respect rate limits with configurable delay and retry on 5xx/429
- Skip entries that have no Wikipedia article
- Removed unique constraint on wiki_article (multiple entries can share one)
