Enhance timestamp parsing and arrival data handling in MainUIHandler

- Introduced a new helper function to parse ISO 8601-like timestamps into epoch seconds.
- Improved the handling of timezones, allowing for better accuracy in arrival time calculations.
- Refactored arrival data fetching to ensure UI updates only when data changes.
- Enhanced error handling for arrival data retrieval, providing clearer messages for various error states.
- Updated formatting functions for arrival times to handle both relative and absolute formats more robustly.
