fix(plaza): use hero-generated thumbnails and portal cover URLs

Browse Source 
Plaza posts now resolve cover_url to /u/{slug}/pages/{urlSlug}.thumbnail.png
instead of MindSpace workspace paths that fail on plaza.tkmind.cn. Public-html
and chat quick-plaza flows regenerate workspace thumbnails with force:true
after hero images are on disk so feed cards embed the generated art.
