Is your feature request related to a problem? Please describe.
We are seeing a mismatch between the UI Regular Count and the API regular_count:

UI Regular Count = number of unique people who checked in (deduplicated by person)
API regular_count = number of check-in records, not deduplicated

Because of this difference, summing regular_count across EventTimes or using the EventPeriod regular_count does not match the value shown in the UI.

This makes it difficult to reconcile API data with the UI for reporting and analytics.

Describe the solution you'd like
We would like the API to provide the exact Regular Count as displayed in the UI for each EventPeriod. This could be achieved either by adding a new key to the existing EventPeriod response that returns the deduplicated attendee count, or by providing a new API endpoint that delivers this information directly. This enhancement would allow API consumers to retrieve the same data shown in the UI without additional calculations, enabling accurate reporting and analytics.

Describe alternatives you've considered
Summing regular_count from EventTimes — overcounts when one check-in applies to multiple EventTimes
