New Feature: Interactive ICA trace highlighting via topomap

[iofeii]

Currently, ICA traces are displayed close together, which is great for visualizing the full decomposition. However, this compact view can make it difficult to quickly identify which trace corresponds to a specific topomap.

By enabling direct interaction (i.e., clicking on a topomap to highlight its trace), users can more efficiently inspect individual components.

Expected Behavior:

• Clicking a topomap will highlight the associated ICA trace
• Only one trace should be highlighted at a time
• Clicking an already highlighted topomap will unhighlight the trace
