The popup covers the thing it is reporting on — a circle's own parcels sit
directly underneath it — so it has to be movable to be read against the map.
Pressing the title bar and dragging now moves it.
The drag changes the overlay's offset, not its position. The popup stays tied to
the shape it describes, so panning and zooming carry it along and it goes on
pointing at the right circle; only where it rests relative to that anchor
changes. Setting a new position instead would cut it loose and re-anchor it to
whatever ground it happened to be dropped on.
The resting offset is now a named constant shared with the overlay, so the two
cannot drift apart, and each showing starts from it — a popup opened for a new
shape appears where it belongs rather than where the last one was left.
A press on the close button is not a drag, and the overlay already has
stopEvent:true, so the map does not pan underneath.
This covers the Area Analysis popup too: both are built by the same
_buildAnalysisPopupHtml, so both get the handle.
Separate commit from the radius work so it can be cherry-picked onto main if the
radius entry does not survive the usability check.
