Add medicine management functionality with UI and data handling

- Implemented MedicineManagementWindow for adding, editing, and removing medicines.
- Created MedicineManager to handle medicine configurations, including loading and saving to JSON.
- Updated UIManager to dynamically generate medicine-related UI components based on the MedicineManager.
- Enhanced test suite with mock objects for MedicineManager to ensure proper functionality in DataManager tests.
- Added validation for medicine input fields in the UI.
- Introduced default medicine configurations for initial setup.
