The user pointed out that track layout changes matter most for Open
Practice/training, not races - so the admin Training page and the
driver's own mobile profile (server/public_training_profile.js, the
actual thing most viewed after practice) needed the same layout
scoping already applied to the live "track record" audio cue.
Every stat now splits into two groups: lifetime/commitment numbers
(total laps, sessions, training days, milestone badges) still read a
driver's whole history, since a track rebuild doesn't erase past
practice. Pace/record/consistency numbers (personal best, recent-pace
trend, consistency spread, the "stable pace" control zone, stint
achievements, "best stint") now read only laps tagged with whichever
layout is currently active. Each ledger entry is tagged with
trackLayoutId at the moment it's synced from a session, so it survives
the source session later being deleted.
Verified with new unit tests covering both implementations and a real
headless-browser run confirming both the admin page and the actual
public mobile profile show the current-layout best lap (never a
faster but incomparable old-layout one) while keeping the correct
full lifetime lap count in both places.
