Gate search behind CompanySettings.searchEnabled; fix two reported bugs

Search icon now gated behind the new backend toggle, same pattern as
wishlistEnabled — off by default.

Fixed: blog category filter bar was invisible — it was wrapped in
<Reveal>, which sits right at/just past the hero's bottom edge, the
exact "already near the initial viewport" position Reveal.tsx's own
comment documents as a whileInView(margin:"-80px") trap (an element
already visible without scrolling can permanently never register as
"entered view", since `once: true` never gets a second chance). Now a
plain div, no scroll-reveal animation needed for a filter bar anyway.

Fixed: wishlist count showing one behind on the Navbar badge —
useWishlist.ts's toggle() broadcast the "refetch me" event immediately
after the optimistic local update, before the POST request was even
sent. Another instance's resulting refetch could race the actual
server-side write, get the pre-toggle list, and then never get told to
refetch again. Broadcast now only fires after the request settles.
