Personalized social previews for shared referral links

Browse Source 
/my/:id and /join/:id are now served with server-injected, per-member
Open Graph + Twitter Card tags (social scrapers don't run JS, so the
per-ID meta must be in the static HTML). Strips any baked-in og/twitter
tags and injects a fresh ID-specific set — title/description reference
the member #, branded og-card.jpg image, canonical per-ID og:url. Bare
/my and /join paths unchanged.
