fix(metrics): update AvgLatency type and improve SQL query for metrics retrieval
- Changed AvgLatency field type from int64 to float64 in HistoricalMetrics for better precision in latency measurements. - Updated SQL query in GetRecentMetrics to ensure proper averaging of AvgLatency by casting to float, enhancing accuracy in metrics reporting. - These changes improve the reliability of metrics data and ensure more accurate performance monitoring.
