refactor: update dashboard types and schemas for improved validation

- Removed unused import for `createMetricsRawLlmMessageEntry` in visualization tools.
- Introduced Zod schemas for `Dashboard` and `DashboardConfig` to enhance type validation and structure.
- Cleaned up the interface definitions for better clarity and maintainability.

These changes improve the robustness of the dashboard configuration and streamline the codebase.
