- Convert AmtrakDateFormatting API from static to instance properties/methods and added parsedDate(from:) to return Date.
- Update time(from:) and date(from:) to instance methods. Improve isOnTime logic to compute actual vs scheduled differences (minutes/hours) and report early/late/on-time.
- Updated ContentView to create an AmtrakDateFormatting instance and use the new API. Remove the Train.serviceDate extension.
- This update adds ISO date/time helpers for Amtrak timestamps, refactors the train table to show arrival time, status, and track details, and tracks the current station context in the UI.
- It also hardens station status decoding with a safe fallback to Unknown and simplifies the row model to match the new display.
