Create a way for table reports to optionally include diagrams

Tagging Florida Drupal Camp 2024 where this was worked on.

This has been completed. Table reports now have optional calls to getPreReport() and/or getPostReport() which can return any render array including mermaid charts,

I also added HR tags to separate the pro and post content if it appears.
This will go out in the next release.

This is complete and released.
