Subject: Fix WhatsApp/OG link previews: https URLs and correct image
 dimensions

nginx was sending X-Forwarded-Proto: http (its own scheme) rather than
https (the edge scheme), so og:url and og:image were http:// URLs.
Fixed by hardcoding https in the nginx proxy_set_header since HTTPS is
always terminated at the upstream Apache router.

Added a 1200x630 landscape og-default.png (WhatsApp requires ~1.91:1
ratio) and explicit og:image:width/height meta tags. Also tracks the
nginx site config in the repo.
