fix(polymarket): correct sports/tech/finance categorization + widen 90d window

- Add European football leagues (La Liga, Premier League, Bundesliga, etc.)
  to _SPORTS_EXCLUSIONS so those markets are filtered before category detection
- Reorder _detect_category: check tech before crypto/finance so company-specific
  markets (OpenAI IPO, NVIDIA, Apple) resolve to "tech" instead of "crypto/finance"
- Widen resolution horizon default from 60 to 90 days to surface more
  markets in the 0.08–0.92 uncertainty zone
