feat(chat): Obsługa linków wewnętrznych i lepszy badge thinking

- Dodano style CSS dla forum-link (fiolet), news-link (zieleń), b2b-link (żółty)
- formatMessage() obsługuje teraz linki wewnętrzne (/forum/, /news/, /b2b/)
- Badge thinking pokazuje opis jakościowy (np. "dogłębna analiza z weryfikacją")
