Add mobile touch support for elevation chart interaction
- Single touch + drag: scrub the highlight point along the chart,
  map dot follows in real-time
- Tap: pan map to that point (10px threshold for movement)
- Two-finger touch: range select — area between fingers highlighted,
  on release zooms map to fit that route section
- touch-none CSS + preventDefault prevents page scrolling on chart

Spec updated with mobile touch interaction scenarios.
