Add news pipeline: hourly scraper + Gemini summarizer in compose
Vendor the newsPipeline scraper + summarizer into the repo and wire them into
docker-compose against the EXISTING osint-db (no second Postgres), replacing
the upstream k8s CronJobs with in-compose wall-clock loops (:00 scrape, :05
summarize).

- news/scraper: vendored Scrapy project (257 RSS feeds) + hourly loop
  scheduler (run_news_scraper.py)
- news/summerizer: vendored Gemini map-reduce summarizer, cleaned:
  * fix broken google-genai response handling (_extract_text, defensive)
  * fix malformed INSERT/GRANT query in save_summary_to_db
  * OSINT-neutral default MAP_PROMPT; futures/markets language gated behind
    INCLUDE_FUTURES=0 (yfinance lazy-imported)
  * env-configurable model, batch size, lookback window
  + hourly loop scheduler (run_news_summarizer.py, :05)
- alembic 003_news: idempotent articles + article_summaries tables
- API: GET /api/news and GET /api/news/summaries (+ models, schemas)
- tests/test_api_news.py: 5 DB-backed contract tests (all pass vs real PG)
- docs/news.md + .env.example updates

Both services run under the `ingest` compose profile (matching the
ingester/camera-scraper pattern) and build arm64 on the Pi via the existing
Forgejo CI workflow. telebot left out of scope (reserved env only).
