Consolidate Admin Logs Hub

- Implement new unified monitoring hub by adding EdgeFunctionLogs, DatabaseLogs, CorrelatedLogsView, and UnifiedLogSearch components
- Integrate new tabs (edge-functions, database, traces) into ErrorMonitoring and expose TraceViewer route
- Update admin sidebar link to reflect Monitoring hub and extend error modals with log-correlation actions
- Wire up app to include trace viewer route and adjust related components for unified log correlation
