feat(mobile): add the phone-tuned Cesium globe engine

createGlobe() implements the Globe API in mobile/DESIGN.md: Esri day
imagery blended with NASA Black Marble night lights across the
terminator, Google 3D tiles below 25 km when keyed, a single-pass
grade with half-res bloom and lenses, an adaptive quality governor,
live layers on the repo's /api routes and parsers, time scrubbing,
picking, AR contact queries and live situation cards.
