Integration tests issue with required auth level != 1

### Description

If a test app is configured to have required authentication level 2,3, or 4, then a e2e test will fail it's auth againt the app as the authenticationLevel option in cy.startAppInstance seems to always give 1, no matter the value provided.

A simple workaround is to make the test app require auth level 1.

Start by tracing the cy.startAppInstance entry point and how its authenticationLevel option reaches the test app. Reproduce the failure with required authentication levels 2, 3, and 4, then verify that the e2e tests authenticate successfully for each configured level.
