Refactor frontend components and contexts for improved structure and functionality

- Removed unnecessary comments and documentation from CardContainer, Header, HistoryCharts, MenuButton, PollutionMap, SideMenu, SummaryCards, and ThemeButton components.
- Updated import paths to use aliasing for cleaner code.
- Replaced the old context implementations (ConfigContext, DataContext, ThemeContext) with new hooks and context structure for better state management.
- Introduced a new axios instance for API calls to streamline requests.
- Added new utility functions for date and error parsing.
- Updated the main entry point and pages to reflect new context and component structures.
- Created new configuration files for development and production environments.
- Enhanced data fetching logic with improved error handling and loading states.
