feat(wind): render the inspection marker from a store

createWindInspectionMarker() moves to src/layers/wind/inspectionMarker.js,
so the portable ./tools entry that reads wind/inspection.js stays free of
Vue. It keeps the frame listener and projection and presents where the
inspected point falls to the gev-wind-inspection store after each
rendered frame, publishing nothing for an unchanged frame; the scene
chrome teleports the marker into the wind layer's container with the
same class, inline style, hidden state and position. The application
guide lists everything leaving out the scene chrome now leaves out.
