fix(compare): sticky school bar hidden behind the site header

The Navigation header is position:sticky top:0 (z-index 1000). The school
bar was also sticky top:0 (z-index 10), so when scrolled it pinned at the
same top:0 *behind* the header — on mobile 57 of its 72px were covered,
leaving only a sliver, so you couldn't see which schools were selected.

Offset the bar's sticky top to the header height (65px desktop, 57px
mobile — the Navigation breakpoint is also 640px) so it pins just below.

e2e guard asserts the bar's sticky offset is at least the header height
(verified it fails against the pre-fix build).
