[Deprecated] This endpoint is misnamed and does not actually replay events. Use `GET /webhooks/events?caseId={id}` to inspect delivery history, then `POST /webhooks/events/{eventId}/replay` to re-deliver a specific event.

This endpoint was never fully implemented — it counts cases created since sinceUtc and returns the count as eventsReplayed, but does not re-enqueue or redeliver any events. The name "replay" collides with the real POST /webhooks/events/{eventId}/replay endpoint which actually re-delivers.

This endpoint is kept for backward compatibility (additive-only rule) but is deprecated. Integrators should migrate to the event-log + replay-by-id pattern described above.
