feat(editor): visualize patrol path of selected NPC as ribbon with waypoints

Browse source 
Adds setPatrolPath() that draws a multi-segment orange ribbon between the
NPC's spawn position and each waypoint, plus diamond markers at each point
(green for start = NPC home, white for waypoints). Renders only while the
NPC is selected and has a patrol path defined.
