fix(globe): tighten the Cesium engine after review

Map sources are applied through one src/maps/sceneApply.js helper shared by MapSourceController and engine.maps (live layer kept for an unchanged provider, providers cached per source). The contract gains flyTo endTransform and rectangle destinations, flyToSphere easing, drillPick width/height and pick content, with Cesium's own flyToSphere range. Input skips listeners removed during dispatch and stays inert after destroy.
