Vendor toggle + buy-now URLs

The seller's switch

In the seller panel, Settings → Catalog Mode has a switch. The text says that the Add to cart button disappears and products show a Buy now link or Request quote button. That is not the case yet — products stay buyable.

Buy now links

Each product is meant to have its own Buy now web address (for example the product on the seller's own website). There is no screen to enter it yet, in the admin or the seller panel.
