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.
