refactor(kanban): enhance layout and overflow handling in KanbanCard component

- Updated CardHeader to use a block layout and added conditional padding for better spacing.
- Modified title and description elements to handle overflow, ensuring text remains within bounds.
- Improved agent info panel layout with flex-wrap for better responsiveness.
- Enhanced summary section with overflow handling and consistent spacing for a cleaner UI.

These changes improve the overall presentation and usability of the KanbanCard component.
