When a bill page opens with no stored articles, the backend queues a
fetch_news_for_bill Celery task and returns immediately. Added a retry
loop (up to 3x, 6 s apart) driven off newsArticles state so articles
populate without a manual refresh. Fixed broken useEffect dependency
([billId] → [newsArticles]) that caused the timer to never fire.
News is now fetched via a separate useBillNews query (staleTime: 0)
independent of the cached bill detail response.

Adds Google Trends, NewsAPI, and Google News RSS scoring for members,
mirroring the existing bill interest pipeline. Member profiles now show
a Public Interest chart (with signal breakdown) and a Related News panel.
Key changes:
- New member_trend_scores + member_news_articles tables (migration 0008)
- fetch_gnews_articles() added to news_service for unlimited RSS article storage
- Bill news fetcher now combines NewsAPI + Google News RSS (more coverage)
- New member_interest Celery worker with scheduled news + trend tasks
- GET /members/{id}/trend and /news API endpoints
- TrendChart redesigned with signal breakdown badges and bar+line combo chart
- NewsPanel accepts generic article shape (bills and members)
