The Course message advertised capabilities=0x04 (time only), telling
consumers the course had no position data. Wahoo accepted the route
(distance/elevation come from request fields) but rendered an empty
map. Set capabilities to valid|distance|position (0x1A).
Also write a real lap totalElapsedTime/totalTimerTime derived from the
1Hz record timestamps; a zero-duration lap can be rejected as malformed.
