Two visible cues when the user starts tracking without a fix: 1. The Enter alert now reads "Waiting for GPS fix" instead of "Tracking started" when the LocationProvider isn't valid at the moment of toggling. Tracking is still armed — sampling starts as soon as the GPS lock comes up. 2. The Summary Status field shows "waiting fix" while active and the ring is still empty (no point ever sampled). It flips to "tracking" once the first point lands. The detection is "any point recorded yet?" rather than "is the fix valid right this second", which is stable across the cadence of UITask::loop sampling.
