Add Sport/Canada/US/AI/Cloud/HomeLab pills; drop Finance

- New Sport pill: detect sports by clear headline terms or majority
  sports-outlet sources, and exclude sports (and F1) from All/Tech/regions so
  World Cup/soccer no longer pollutes Finance/Tech.
- New client keyword pills: Canada, US, AI, Cloud, HomeLab (headline-matched).
- Remove the Finance pill; keep Tech (backend topic).
