Website: products, library, catalogs and their console page

/products (search), product pages with revisions, getting and staying on a
revision, retracting; /products/:id/edit; /create and new revisions upload
from the browser straight to the catalog with a token from the hub;
/library; /catalogs (directory, registering with a once-shown key);
/console/catalogs to approve or reject. Every page now sends a nonce-based
CSP (proxy.ts), so product descriptions can't run scripts.

buttonVariants now merges classes, so outline links get their border.
