[Scenario Bundles] Users not logged in are not redirected to the login page if they attempt to access restricted funtionalies

[jh-RLI]

Description of the issue

Some functions, such as the creation of a scenario bundle, are restricted to registered users. They are expected to be redirected to the login page and back to the original page after logging in. This behavior is not possible without additional changes, as the Bundles app was developed with React. This requires additional code.

Steps to Reproduce

1. Navigate to scenario bundle page
2. Log out
3. Click "create scenario bundle"
4. Insert acronym and click create
5. Load sinner for ever .... (it is possible to go back from here)

Ideas of solution

• Provide an endpoint to which the React frontend can send an http request and check if the current user is authenticated.
• Implementation of JWT token-based authentication

The React frontend must be integrated into the authentication workflow.

Context and Environment

• Version used: develop
• Operating system: linux
• Environment setup and (python) version: default, 3.9

Workflow checklist

• [ ] I am aware of the workflow in CONTRIBUTING.md
