feat: Modularize KueModal component by extracting handler functions

- Moved `handleSave`, `handleChange`, `handleDisplayEinschalten`, `handleSetDateTime`, `handleClearDatabase`, and `handleReboot` to separate handler files for better modularity and code organization.
- Updated imports in `KueModal.jsx` and `SettingsModal.jsx` to use new handler files.
- Improved code readability and maintainability by organizing functions into dedicated handler modules.
