A .geojson file needs no GPX/FIT conversion — it's already the shape gpx.js expects — so GpxStore#geojson now just reads and returns it as-is, no cache sidecar. save/tree/the upload dropzone and its zip handling all pick it up through the existing TRACK_EXTENSIONS list. Also fixes a bug the new "cached" tree icon would have shipped with: a GPX/FIT's own .geojson cache sidecar (e.g. "ride.gpx.geojson") also matches the new .geojson branch in list_children, which would have listed it as a second, phantom tree entry — excluded explicitly, with a regression test.
