Add Vercel-style deployment dashboard

- Add /deployments/[uuid] route with detailed deployment view
- Add DeploymentDashboard component with tabs (Deployment, Logs, Resources, Source)
- Add real-time health/stats via SWR with 10s polling
- Add Docker API helpers (health, stats, uptime) via SSH
- Add redeploy action endpoint and button
- Add expand button to table for inline log viewing
- Add loading skeleton, error, and empty states
- Handle edge cases (in_progress, error, cancelled, missing data)
