Refactor the login on moderation into the cypress.config.ts

[NabbeunNabi]

Problem

Currently the login process in the tests for the Moderation Panel do not follow the recommended structure in the Cypress Documentation for using OAuth. This could be slowing down our tests and it would be better to use the method in the documentation above.

Success

The login process is refactored from our current usage in the tests to the usage in the documentation listed above. It is then used in the tests with all the tests for the moderation dashboard passing

Requirements

• Refactor login process according to the Cypress Documentation
• Update the tests for the moderation dashboard using the refactored login process
• Have all the tests passing with this new process
