TrackStats.build_profile now also computes elapsed_secs per point (relative to the first known timestamp), alongside the existing cumulative distance. Point x-positions stay distance-based either way — only the shared axis strip's 5 tick labels (and the tooltip) switch between the two, so toggling is a cheap re-render rather than rebuilding the charts. The toggle only appears when a track actually has elapsed-time data to switch to.
