feat(cockpit): keep the orbital camera on a ground target

In the satellite orbital view a single click on a mapped ground point (a
ground point of a layer that is on, such as a Mapped Installations site, a
fire or a local data pack feature) keeps the camera on it. Each frame the
look is aimed from the satellite's position to the point's Earth-fixed
position in the track-up nadir frame the arrows tilt, so the point stays
at the centre as the satellite moves. The swing onto the point, or between
points, uses the arrows' easing on a slower clock and then holds the point
exactly; reduced motion cuts.

A click elsewhere, FOCUS on the focused point, NADIR, Home or 0 ends the
focus and the view eases back to nadir; an arrow ends it and tilts on from
where the view is. The focus also ends, easing back, when the point leaves
the ±45° reach or the satellite's horizon, when its layer is turned off or
its record is dropped, and with the view. While focused the readout gives
the single off-nadir angle to the point (OFF-NADIR 23.4°), names it in a
polite live region, and the swath reads approximate as for a tilt. Clicks
still reach Cesium's own handler and never untrack the satellite; a click
a tool owns is ignored.

Under the readout, IN REACH lists the mapped points facing the satellite
that are within the reach or in the frame, nearest to nadir first and at
most 12, rebuilt once a second. A row opens the point's position, source
and OpenStreetMap tags (or its layer's properties); FOCUS focuses it,
switches to it, or ends the focus held on it, and is unavailable for a
point in frame but beyond the reach.
