feat: replace Kaggle CSV with Wikipedia scraper for historical match data

Add scripts/scrape-wikipedia.ts that fetches all 22 World Cups (1930–2022)
from English Wikipedia via MediaWiki API, handles group sub-pages, AET/penalty
detection, and goal parsing, writing openfootball-format JSON to app/data/openfootball/.

Rewrite scripts/seed.ts to read these local JSON files instead of the Kaggle
CSV, producing 965 matches and 2716 goals with per-group assignments for all
historical tournaments (enabling group standings on tournament pages).
