Refactor application structure and components

- Moved components to a new layout directory for better organization.
- Updated App component to include GroupView and adjust routing.
- Removed unused components (App.jsx, Card.jsx, CardContainer.jsx, Header.jsx, MenuButton.jsx, SideMenu.jsx, ThemeButton.jsx).
- Introduced LoadingIcon component for loading states.
- Updated PollutionMap, SummaryCards, and HistoryCharts components to accept groupId as a prop.
- Modified API endpoint configurations in settings.prod.json for better clarity and consistency.
- Enhanced chart options in historyChartConfig for improved visual representation.
- Updated favicon and logo images.
