Replace FastF1 with Jolpica API for circuit resolution

FastF1's get_event() couldn't resolve several grand prix names
(Qatar, Brazilian, Mexican, Barcelona), causing 500/404 errors.
Now uses Jolpica's race schedule directly — slugifies circuitName
to match against circuits.json with ASCII fallback for unicode.
