Simple login Patient - Githubissues

As a patient I want to login in the app so that I can use restricted areas like for example assign a doctor and use these features

Context

Patients are using the app. They can use the app to manage their data and confirm doctor assignments. The app is their main channel for getting a insulin dosage recommendation.

In scope

Login with given credentials via app
Use existing backend and extend

Out of scope

Any validation or registration

There are follow up stories for that: https://github.com/diabetes-assistant/documentation/issues/16, https://github.com/diabetes-assistant/documentation/issues/28

Tech notes

Extend existing backend api /api/token
make sure only patients can login in app
show user details when logged in
Maybe change cors settings?
