Replace flat app/route/agent lists with expandable tree navigation.
Apps contain their routes and agents hierarchically. Add localStorage-
backed starring with composite keys for uniqueness. Persist expand
state to sessionStorage across page navigations. Add collapsible
section headers, remove button on starred items, and parent app
context labels. Create stub pages for /apps/:id, /agents/:id,
/admin, /api-docs. Consolidate duplicated sidebar data into
shared mock. Widen sidebar from 220px to 260px.

Rename all references from "Execution/executions/execCount" to
"Exchange/exchanges/exchangeCount" to align with Apache Camel's
native Exchange concept. Java class names (CamelExecutionException,
HttpOperationFailedException) are preserved as-is.

Implements the /metrics route with DateRangePicker bar, 5 KPI StatCards
with sparklines (throughput, latency p99, error rate, success rate,
active routes), per-route DataTable with trend sparklines, and a 2x2
chart grid (AreaChart throughput, LineChart latency with SLA threshold,
BarChart errors, AreaChart volume). Uses AppShell + Sidebar + TopBar
layout with mock data from src/mocks/metrics.ts.
