Implements the /routes/:id route with route header card (name, status
badge, description), 5-card KPI strip (total executions, success rate,
p50/p99 latency, inflight count), ProcessorTimeline showing aggregate
processor stats across all executions, filtered DataTable of recent
executions for the route, and error patterns section grouped by
exception class. Uses useParams() to get route ID and navigates to
/exchanges/:id on row click.
