- Rename Metrics to Routes with /routes, /routes/:appId, /routes/:appId/:routeId
- Sidebar: Routes is now a collapsible tree (apps > routes) like Applications/Agents
- KPI header matching mock-v3-metrics-dashboard: throughput with sparkline, error rate,
latency percentiles (P50/P95/P99), active routes with mini donut, in-flight exchanges
- Same KPI header used consistently across all 3 levels with scoped data
- Route detail level shows per-processor performance table and RouteFlow diagram
- Added appId to RouteMetricRow and filled missing route entries in mock data
- Fix sidebar section toggle indentation
