Implement dose tracking functionality and enhance CSV migration

- Added a new migration script to introduce dose tracking columns in the CSV.
- Updated DataManager to handle new dose tracking columns and methods for adding doses.
- Enhanced MedTrackerApp to support dose entry and display for each medicine.
- Modified UIManager to create a scrollable input frame with dose tracking elements.
- Implemented tests for delete functionality, dose tracking, edit functionality, and scrollable input.
- Updated existing tests to ensure compatibility with the new CSV format and dose tracking features.
