fix(lcxl3): lap 1 starts at first track load, not process construction

The OLED's track clock resets 'a new track is a new lap' — but skipped the
FIRST load, so lap 1 inherited the constructor's zero. Invisible while the
driver restarted with every session; under the persistent unit (log 039) it
counted the idle hours before the first load: 24:27 on a fresh rose_rouge.
