feat(configuration): enhance Vite config for React and Ant Design integration

- Updated Vite configuration to ensure a single React instance and prevent context issues by adding 'react/jsx-runtime' to deduplication.
- Improved manual chunking strategy to keep React core together and optimize Ant Design component loading.
- Adjusted build settings for better source map handling and chunk size warnings.
- Centralized Ant Design imports in `antd-imports.ts` to ensure React is available for all components.
- Removed exclusions for Ant Design to enhance compatibility and performance.
