Expose the reason for a "Not sent" status via the API

When asking the MCP, "How many people have been asked to review in the last 30 days?", the API returns the outcome of an invite (e.g., added, invited, opened, clicked, redirected, etc.), which is great. However, when a contact shows as "Not sent", the API provides no reason for this status.

It would be helpful to include the reason why a contact was not asked (for example, if they were blocked by the 90-day deduplication filter because they had already been contacted three weeks earlier via a reactivation campaign).

Currently, this information is only visible in the EMR contact activity timeline, not through the API.
