[feature]: Colorful Minimap

### Tell us about the problem you're trying to solve

### Describe the solution you’d like

It would be nice to use the functionality of react-flow inside the minimap to color triggers, flows and components.

### Describe the alternative you’ve considered or used

### Additional context

https://reactflow.dev/api-reference/components/minimap#customising-mini-map-node-color

Locate the minimap implementation and read the linked React Flow custom mini-map node color documentation first. The work is done when triggers, flows, and components are visibly distinguished by color in the minimap, matching the requested behavior and example.
