fix: jam link previews showing generic plyr.fm branding (#990)
/jam/ was missing from hasPageMetadata in root layout, so default OG
tags rendered first and crawlers used the generic logo instead of
jam-specific metadata. Also expanded jam OG tags to match track/album
quality (og:type, og:site_name, twitter card, image dimensions).
