refactor(ui,voice,annotations,scenes): take vector maths from src/geo

Move the Cartesian3/Cartographic/Matrix4/Transforms/Ellipsoid/Math calls of
the second batch (cockpit camera, context and controller; camera orientation
controls; application shell; location navigation; the annotation resolver
and engine; voice actions and pointer pick; the scene director; the embed
app) to src/geo. Behaviour is unchanged: same argument order, same `result`
semantics.

Kept on Cesium: out-of-scope classes (HeadingPitchRange, BoundingSphere,
Intersect, EllipsoidalOccluder, EasingFunction, SceneTransforms, JulianDate),
WGS84 where it goes into pickEllipsoid or EllipsoidalOccluder,
Matrix4.IDENTITY handed to lookAtTransform, and the Cartesian2 window
positions that reach scene.pickPosition: Cesium keys its per-frame pick
cache on windowPosition.toString(), which a plain object would collapse to
one "[object Object]" key.

The Contacts-subject harness in gevActions.test stubbed
Cesium.Cartographic.fromCartesian to place its subject; it now builds a real
subject position at the same coordinates with geo.cartesian3.fromDegrees.
The cockpit-controls and scenes package-boundary groups now own the src/geo
files.
