fix(pum): separate scrollbar from shadow border (#37448)

Browse Source 
Problem:
With shadow border, scrollbar and border overlap. Shadow's right border
starts from the second row (offset by 1), but scrollbar renders on every
row including the first. If they share a column, the first row shows
scrollbar where shadow hasn't started yet, causing misalignment.

Solution:
Separate scrollbar from the shadow's right border.
