feat(editor): a tap opens a device's menu in the simulation; undo and redo drawn

In the simulation a tap on a device chooses it and opens its menu where
the finger was; the three-dot button is gone there, the long press stays.
The context menu moves in from the surface's edge instead of being cut off.
Undo and redo show drawn arrows: the characters took whatever font the
device had and looked squashed on an iPad (the buttons measured 44 x 44 at
every width; the size was not the cause).
