POST /products/configs/blocklist

Add a product code to the blocklist

Exclude a product tax code from onboarding suggestions for the resolved organization. Idempotent: blocklisting an already-blocklisted code returns 200 with the existing entry rather than an error or a second 201. Returns 400 if `productCodeName` is not a recognized product tax code, and 409 if it already has a configuration (remove the configuration first). Send the target organization as `Organization-Id` when your credential owns more than one.
