Schema naming does not follow a consistent convention

## What are the schemas that are affected by the issue
`person-name`, `beacon-interaction-details`, `advertising-break`, `direct-marketing`, ...

## What are examples of products that are impacted by the issue
Any product that uses these schemas.

We seem to have two approaches to schema naming:
* concatenate the words without spaces, convert to all lowercase
* separate the names with hyphens, convert to all lowercase

Why are we using different naming conventions? What is the best practice?

Review the affected schema names, including `person-name`, `beacon-interaction-details`, `advertising-break`, and `direct-marketing`, and compare the two naming approaches described in the issue. Determine which convention should apply to schemas and identify the complete set of impacted products or schemas. The issue does not name files or tests, so the scope and completion criteria need clarification before implementation.
