UI feature: add overall progress indicator ("wizard" element)

[isms]

Expected Behavior

We want the users to have a clear path in the workflow:

• Load a case
• Mark all nodules
• Mark any nodules not found if necessary
• Annotate and bound all nodules marked concerning
• Move to report

We should clearly show them at all times a progress indicator showing which phase (step 1/4) and what remains in that phase (2/3 nodules identified).

This should all be fairly easy to calculate from the current Case. Some random images of the kind of element:

Possible implementation

@Serhiy-Shekhovtsov are you actively working on this issue? (Since you upvoted it). Just wanted to make sure we're not colliding.

@louisgv I am not working on it, just like the feature :) Especially if the progress will be saved on loaded. This gives me pain every time I work on interface frontend. Have to go to first step and select the case each time the page is reloaded.

I will start working on this. WIP PR coming soon!
