Add News hub and wire homepage Latest news to a dated content index

New /<lang>/news/ hub aggregates real projects (title+image read from their pages), placeholder news announcements, and blog items, newest-first with type badges and a type filter. Homepage Latest news now shows the newest dated items as badged cards with a working See all to the hub; the News menu link points there too. Dates in news.js are placeholders to replace with real publish dates.
