showSessionDetail's elevation profile, min/max, x-labels and point popup read
only altitude_gps_m, but 'Уточнить высоты (онлайн)' writes altitude_srtm_m
(computeStats already prefers srtm — hence stats updated but the chart stayed
empty). Read altitude_srtm_m ?? altitude_gps_m everywhere the detail shows
elevation, matching computeStats. No regression: no srtm -> falls back to gps.
