feat(training): base training stats on practice, keep race laps separate

Training stats count Open/Free practice by default; laps from
qualifying, heats and finals are kept and shown under Based on: Races
or All, marked with race, session and series. Races are listed per race
session and never split into stints. Same picker in the mobile profile.
