Add feed summary preview and pinned interest filters

- Show a 6-line cross-source summary preview in each feed row.
- Pinned, mutually-exclusive filter pills: All, F1, Uganda, East Africa,
  South Africa, Finance, Tech. "All" is news-only (F1 lives only under F1);
  regions don't overlap (East Africa excludes Uganda & South Africa).
- Categorization correctness: regions match the headline only (the backend's
  summaries/outlets are polluted by over-clustering), and F1 takes precedence
  over every other pill since the backend mis-tags F1 as tech/finance/politics.
- Finance/Tech match the backend topic; sparse filters auto-pull more pages.
