Refactor HistoryDisplay and ModelHistoryDisplay for Improved Layout and Readability

- Reformatted code for better readability by adjusting the structure of the useHistoryLegendOverlay hook.
- Updated padding in Card components for consistent layout across displays.
- Enhanced Flex components with consistent gap values for improved spacing.
- Added overflow handling to div elements to prevent layout issues with chart rows.
- Improved loading state handling for better user feedback when no data is available.
