Add extra Basic Authentication tests in E2E

[andrewortwein]

Issue: #AP-4963

What Changed

There are now two resources that require authentication: /protected and /admin. These resources use different sets of credentials to access them. This ensures that credentials set in a specific test will override global credentials, as supported in Playwright.

There is also a new Cypress test to validate that tests can set credentials to access these protected resources.

How to test

See the Cypress and Playwright auth tests.
