fix v1.37.3: true dashed open boundary, rendered above the glow

- outlineWithout trims the rooms' solid strokes under open stretches
  (.room.noedge kills the polygon stroke incl. hover; trimmed
  .room-outline path draws the remaining walls)
- dash color follows the space stroke color; openwalls layer moved
  after the glow layer
- +1 unit test (105); smoke_openwall extended; docs same-commit
