feat(insta): _bg_extract uses preferences + 09:00 trends_collect cron

- POST /api/insta/trends/collect — background trend collection via trend_collector.collect_all
- GET /api/insta/trends — list external trends with source/category/days filters
- GET /api/insta/preferences — return category weights (defaults seeded on init_db)
- PUT /api/insta/preferences — upsert category weights
- Modified GET /api/insta/keywords to accept source= filter (source present → list_trends, else existing list_trending_keywords, backward compatible)
