fix: clean up imports and enhance dashboard file handling

- Removed duplicate import of ModelMessage in create-dashboards-execute.ts for clarity.
- Updated createDashboardsReasoningMessage function to conditionally include version_number only if defined, improving the handling of dashboard file properties.

All changes aim to streamline the code and enhance maintainability.
