Add a toggle to show or hide module borders in visualizations

[akikuno]

📋 Description

It would be helpful to add a toggle switch for turning module borders on or off in the visualization.

When exporting images as PNG or JPG, having visible module outlines can be useful for presentation and interpretation.
However, in some cases the borders can make the figure look cluttered or distracting.

Proposed feature

Add a UI toggle that allows users to:

• show module borders
• hide module borders
