Train status is now coloured coded for your convenience

- Introduced TrainLateness enum to represent on-time, early, late (with minutes), and unknown states, including description text, color, and formatting logic.
- Replaced TrainStatusRow.status String with TrainLateness and update ContentView to render a colored status pill and to return TrainLateness from isOnTime.
