The wizard's EK / Kundenverkaufspreis fields live inside a
<div class="grid grid-cols-2 gap-md"> wrapper. Toggling its inline
display:block as the previous code did replaced the grid layout and
stacked the two inputs full-width. Switch the wrapper to start with
the Tailwind `hidden` utility and toggle `hidden`/`grid` on the
classList, so when hardware is filled in the two pricing fields
appear side by side. Functionality and the existing commission
formula (Provision + Aktionscodes − EK + VK, already covered by the
provisionService tests) are unchanged.
