Hardcode Cypress APP_URL (Kitware#3639)

Our Cypress tests currently attempt to dynamically set the baseUrl based
on the APP_URL config ahead of time. This doesn't work when the APP_URL
changes mid-run. We already have other mechanisms in place to ensure
that Cypress and Dusk tests don't conflict, so this logic is no longer
necessary. I believe this the root cause of much of the recent Cypress
test flakiness.
