fix: add page navigation to Sidebar + wire in camel SVG logo

- Add Navigation section (Dashboard, Metrics, Agents) with useNavigate
- Route items now navigate to /routes/:id
- Active state highlights current page based on location.pathname
- Replace inline CamelIcon with actual camel-logo.svg asset
