Consider the altitude for break system wear

Enhance the accuracy of brake pad and disc wear predictions by factoring in altitude data from Strava activities. This will allow Geer to better estimate brake pad mileage, especially for users who ride frequently in mountainous or hilly terrain.

Current brake pad mileage estimates are primarily based on distance or time. However, riders who accumulate mileage in mountainous areas experience significantly more braking — especially on long descents — which leads to faster pad wear. This results in underestimating the actual wear for those riders.

Incorporate total elevation loss (descent) as a factor in brake pad wear calculations. Activities with high descent values should contribute more to brake pad wear than flat rides, even if the distance is identical. This could be implemented by introducing a weighting system based on vertical meters descended.
