Replace client-side state switching with proper Next.js routes:
- /new - New scrape form
- /jobs - Jobs list with table view
- /jobs/[id] - Individual job details and logs
- /analytics - Analytics overview (completed jobs)
- /analytics/[id] - Analytics for specific job
Add JobsContext for shared state across routes. Update Sidebar
to use next/link with pathname matching. Root page redirects to /new.
Also adds partial job status styling to JobsView.
