### Is your feature request related to a problem? Please describe the problem.

With Aspire 13 introducing a dedicated Parameters tab, the Resources tab now has a cleaner look. However, the Graph view remains visually crowded because parameters are still displayed inline.

To improve usability and readability, I propose adding a toggle option that allows users to show or hide parameters in the Graph.

### Describe the solution you'd like

- Add a toggle (e.g., checkbox or switch) in the Graph view toolbar.

- Default state could be "parameters hidden" to emphasize clarity.

- When enabled, parameters should be displayed alongside resources as they are today.

### Additional context

Benefits:

- Provides a cleaner, less cluttered Graph view.

- Gives users control over how much detail they want to see.

- Aligns the Graph experience with the streamlined Resources tab.
