Add DM Sans font integration and enhance dashboard context

- Added DM Sans font to the project, including multiple weights and styles for improved typography.
- Updated package.json and package-lock.json to include @fontsource/dm-sans dependency.
- Enhanced dashboard context to include current cluster CPU state, integrating new data into the context and API responses.
- Updated relevant templates and JavaScript to utilize the new current cluster data for better visualization and user experience.
