Add shelves page to game library; refresh bggpipe export

Port the export's physical shelf layout (.wall/.orow/.ocell) into the
scoped embed.css so /mygames/?g=shelves renders the wall in true
proportions, using the cream board color and accent-purple links for
legibility on the dark theme. Includes a fresh bggpipe re-export (new
Etherfields and Red Dragon Inn titles, updated art). embed.js/embed.css
are untouched by the export.
