fix(raw): impossible to see matrix containing NaN values

[MartinBelthle]

In the file raw_studies_blueprint.py, i "rollbacked" the behaviour as it was before this PR: #1577 to allow NaN values in matrices.

I added an integration test to ensure this worked.

I've also cleaned a bit the test_integration.py file:

• I used the fixture admin_access_token when needed
• I added a line admin_headers = {"Authorization": f"Bearer {admin_access_token}"} at the beginning of each test to use this value everywhere and by doing so, I lightened the code

I tried to use ORJSONResponse but that converts NaN to None and we do not want that. Therefore, i keep the code as it is

You are right: it is written in the documentation.
However, we could use orjson for its performance, but it doesn't work for those values 👎🏻
