Adds end to end testing using Cypress and Vitest unit tests

[KSJaay]

Summary

As Lunalytics grows, the chance of one change breaking other parts of the application also grows. I've decided to add end-to-end testing using Cypress to make sure that core features don't break. For now, this will include registering, logging in, adding a monitor, and lastly verifying users. Once more changes have been made to the settings page, more tests may be added.

I've also ended up adding some unit tests for the middleware to make sure the API is working as expected. As time goes on I'll also add tests for the classes, database, and other server-side functions.

Changes

• Adds setupDatabase function to create test database
• Adds testing for register, signin, monitor, and verify
