Subject: [PATCH 1/3] Update application_helper.rb

Fixed `point_speed` in `application_helper.rb` to properly convert velocity from m/s to km/h, round to 1 decimal, and safely handle nil or zero values.

Subject: [PATCH 2/3] Update helpers.js

Updated `formatSpeed` in `helpers.js` to correctly assume incoming speed is in m/s and convert to km/h before formatting.

Subject: [PATCH 3/3] Update _point.html.erb

Patched `_point.html.erb` to use `point_speed(point.velocity)` for consistent and accurate speed display with units.
