Add new response types and parameters for logs API: - Add GroupedStatsItem and GroupedStatsResponse definitions - Add ListLogsResponse and LogView definitions for detailed log records - Add group_by enum parameter (model/day/month) to stats endpoint - Update endpoint descriptions to clarify response types and request_body inclusion - Update response schema references to use correct types
