SSO requests - frontend app

E2E tests

To run the e2e tests, first create a file cypress.env.json in the app directory. For the contents, see the sso-requests-e2e-secrets secret in the tools namespace. Then:

1. Run yarn form the app directory if not installed npm dependencies yet
2. Start a local app and keycloak instances with docker-compose up from the root directory.
3. Once running, run npx cypress open from the app directory. This will open a UI where you can choose which testfile to run
