Add Cypress and basic tests

[dgading]

This PR adds basic tests to make sure pages are loading with the correct data. It is a bit brittle right now since I had to use data from my local and if that changes, some of the tests could break.

Since I still have the pending ticket for updating the interactivity of the goal search, I decided not to include those tests in this PR since all of them would need to be rewritten when the changes are added.

To run the PR:

1. In a terminal start your site at localhost:3000 (can be changed in the cypress.config file if needed)
2. In a second terminal navigate to the tests folder and run npm install
3. After installation, run npm run cy:smoke to run all the tests.
4. To use the visual tester, you can run npm run cy:open to open the Cypress application.
5. All tests should be passing.
