How to debug CJA integration

Issue in ./help/main/c-integrating-target-with-mac/cja/target-reporting-in-cja.md

The documentation does not contain any reference on how to debug the implementation. For example:

- where the events come from? Is there anything needed from a WebSDK implementation perspective?
- where are the information passed from Target to AEP?

The guide explains only the how to setup the connection with the classification data. All the other details of the implementation are missing.

Start with ./help/main/c-integrating-target-with-mac/cja/target-reporting-in-cja.md and review its existing classification-data setup guidance. Trace the documented event source, WebSDK requirements, and information flow from Target to AEP. Done means the guide includes practical debugging details for each of these areas.
