Set mounting height and skirting preferences for new units

Use elevation and skirting visibility preferences so new units start at the right height with the right skirting shown.

1. Base-unit and wall-unit elevation preferences also set the initial mounting height of the new unit (wall-unit elevation is measured accounting for skirting height).

3. When the skirting visibility preference toggle is on, the show/hide state set for front, left, right and back skirting is applied to a unit when it is added, so new designs pick it up.
