There's no way to copy a catalog from test mode to live. Everything proven in test has to
be recreated by hand in live - products, discounts, webhook endpoint config - and retyping a proven configuration is exactly where a typo enters. ("Clone a product" helps within a mode, but not across them.)
A "copy to live" (and back) would close it. We ended up building our own sync script
against the products API partly for this reason, and it can't carry the license-key
settings because those are dashboard-only.
