fix(editor): a block boundary drawn places its signal across only where the other track runs near, the hover and the click count the block signals facing the trains alike, an SHP resonator at a joint finds the piece of a track cut for another one, and a batch of signals missing its template changes nothing but the tracks cut, Ctrl+Z taking them back; the km of each line kept for the hover, the shorter block section named in its warning, the block column wider
