Add profile extension in campaign namespace, to support Journey AI scores

## What are the schemas that are affected by the issue
extensions/adobe/experience/campaign

## What are examples of products that are impacted by the issue
Adobe Campaign

We have created 2 schemas and 1 Profile extension ( in _customer namespace ) to publish Journey AI scores to ACP. We want to add these schemas and extensions to the campaign namespace.

Start in extensions/adobe/experience/campaign and inspect how existing schemas and profile extensions are organized, including the customer namespace reference in the issue. Identify the two schemas and profile extension for Journey AI scores, then verify they are represented in the campaign namespace for Adobe Campaign.
