Three-level dashboard driven by sidebar selection: - L1 (no selection): all-apps overview with health table, per-app charts - L2 (app selected): route performance table, error velocity, top errors - L3 (route selected): processor table, latency heatmap data, bottleneck KPI Backend: 3 new endpoints (timeseries/by-app, timeseries/by-route, errors/top), per-app SLA settings (app_settings table, V12 migration), exact SLA compliance from executions hypertable, error velocity with acceleration detection.
