Consider executing parts of tests programmatically instead of in the browser to speed up tests

[jf-x-dev]

So for example:

• Consider using Playwrights Authentication state for one account per worker
  • Could allow a worker to login just once which would remove the need to login for every test
• For basically all "setup" fixtures we could consider executing these programmatically, e.g. via API calls
  • The setup parts (e.g scheduling a session) are often covered by their own tests, so there is no need to run them in the browser
