fix v1.33.4: device icon stays in place when rebinding or changing room

- rebinding migrates the layout position to the new marker id instead of
  recentering; room change within the same space keeps the position
  (owner's decision); new icons and cross-space moves still center
- smoke_marker_stay.mjs; TESTING/CHANGELOG same-commit
