feat(editor): F4.4b the design tools: palette, moving, cables, menus, undo

The palette in Java's order with Java's icons and names: a device dragged
onto the surface lands with its icon at the drop point, a tapped one in the
middle of the view; a new router asks for 2 to 8 interfaces as Java does.
A tap selects, a drag moves (divided by the scale), a long press or the
three-dot button opens Java's menu. The cable tool plugs by a drag or by
two taps, shows WAN or LAN on a home router's halves and Java's messages
when refused. Delete removes the selection; undo and redo by button and
Ctrl+Z/Ctrl+Y, each editor with its own origin. Browser tests with mouse
and touch.
