Verify Copilot setup

[pylipp]

We recently compiled .github/copilot-instructions.md in #2292

Verify that the setup works.

1. Run the documented primary method to set up the dev environment via docker-compose
2. Verify that you can open the app at http://localhost:3000
3. Verify that you can log in with the provided email and password (login flow test)
4. Verify that you can take a screenshot of the Statistics Dashboard and attach it to the PR

IF THE ABOVE DOES NOT WORK FOR WHATEVER REASON, document exactly what you did and which errors you encountered and which problems need to be solved.

Also, if the above does not work, do the following:

1. Run the alternative setup for local development
2. Execute the verification steps 2.-4. from above

Again, IF THE ABOVE DOES NOT WORK FOR WHATEVER REASON, document exactly what you did and which errors you encountered and which problems need to be solved.

Finally, in one of the working environments

1. make a minor change to a tsx file in /front and verify that you can commit it
2. make a minor change to a python file in /back and verify that you can commit it

IF THE ABOVE DOES NOT WORK FOR WHATEVER REASON, document exactly what you did and which errors you encountered and which problems need to be solved.
