Draw climb profile sections where the slope changes

Fixed distance buckets averaged short steep ramps into their bucket: a
300 m @ 12 % pitch inside a 10 km climb reported ~7-8 % for 500 m. Sections
now come from the base-grid elevation polyline split at its widest bends,
up to a 24 section budget, so ramps keep their own step and label.

Labels are dropped only when they would collide, and the distance axis uses
a uniform 0.1-10 km step instead of one tick per (now irregular) section.
