feat(case): split the plan section into plan_up and plan_down

Browse Source 
Factor the two halves of the horizontal cut into shared modules so each
can be viewed alone (`plan_up` = deck/screen, `plan_down` = cavity),
while `plan` keeps the exploded combo. Cut height and gap are now the
`plan_z` / `plan_explode` params.
