List information request activity

Retrieves a paginated list of activity logs for an information request, providing a complete audit trail of all changes and actions.

This endpoint supports delta synchronization via the changedSinceDate parameter, allowing efficient polling for changes without retrieving the entire dataset.

Pagination usage:

1. Make initial request with desired pageSize
2. Check results.pageInfo.hasNextPage to see if more data exists
3. If true, use results.pageInfo.endCursor as pageCursor in next request
4. Repeat until hasNextPage is false

Delta sync usage:

1. Store the timestamp of your last sync
2. Pass that timestamp as changedSinceDate
3. Only activity created since that timestamp is returned
4. Process updates to track all changes to the information request
5. Update your last sync timestamp to the current time
