Update the menu (#208)

TODO

Symptom check menu entry in patient

One issue I had, is that for the symptom-check entry, this should appear in the HCP app, but not in the patient app. However the module in which the menu entry is provided also provides the route entry (which we'll presumably still need for the patient app)

As such I'd assume we need to decouple this module, so that the patient app can still have the menu entry, but both apps can have the route definition. I think this could be done in a follow up issue. What do you think?

Fonts

The designs use a different font for the navigation bar, however as this font is also used elsewhere, I assume this can be done in another follow up issue
