[FEAT] add panels to display different results

[assynour]

Is your feature request related to a problem? Please describe.
Currently there's one panel for displaying the results of both "discovery" and "conformance checking". As a result, it's not possible to switch between different visualizations. For example, if we're in the "conformance checking" visualization, it's not possible to switch back to the "discovery" visualization. The only solution we have is to press on "discover BPMN" button and to resend the request to the backend.

Describe the solution you'd like
Add two panels, one for "discovery" and a second for "conformance". The panels' content are updated only if the buttons "discover BPMN" or "compute conformance" are clicked.
