Add /products (list + detail) and /blog (list + detail) routes backed by
the real Meshkee API, a real category-hierarchy mega menu (level 2/3 only),
debounced instant search proxied through a same-origin API route, and
tel:-link fallbacks on product cards when no price is set. Also fixes
Product price normalization to read the real API shape instead of a
guessed one, and hardens product linking against catalog sources that
don't expose a slug.
