Add global Deployments dashboard with expandable logs

- New Deployments tab showing all Coolify deployments
- TanStack Table with sorting, filtering, pagination
- Status badges (Ready/Building/Error/Queued/Cancelled)
- Application and status filter dropdowns
- Expandable rows showing build logs in real-time
- Auto-refresh every 10 seconds when tab is active
- Log polling every 2 seconds for in-progress deployments
- API routes that query Coolify database directly via docker exec
