Backend (health_monitor.py):
- Skip health checks for instances with no container_id
- Treat 'not_found' as error only when container was previously running
- Skip duplicate error notifications when already in error state
- Skip 'not_found' notifications for containers that never ran
Frontend (notification-item.tsx):
- Display notification.message (detailed error text)
- Add expandable Details section showing metadata (exit_code, previous_status, etc.)
- New CSS styles for message and metadata display
Quality gates: py_compile, tsc --noEmit, 80/80 tests pass
