Feature/350 switch to vite

[cschwinderg]

Related Issues:

• EQ-350
• EQ-441

Main Changes:

• Switched from create-react-app to vite.
• Fixed issue of 404.html and 500.html pages not loading epa-template-files resources.
• Updated the db ssl logic to work of an environment variable instead of NODE_ENV to make it easier to connect to dev/stage/prod databases from local env.
• Added server side code coverage.
  • Note: I deleted the api-request.cy.ts tests, because I moved these to the server side tests. When these tests were in cypress they didn't really impact coverage much.
• Added more tests to get code coverage above 80%.

Steps To Test:

1. Add DB_SSL=false to the etl/.env.local file
2. Run the etl locally and verify it works
3. Run npm run setup from app folder
4. Add DB_SSL=true to the app/server/.env.local file
5. Update other variables to point your local environment to the dev database
6. Open an ssh tunnel to the dev database
7. Run npm run dev to start the app
8. Manually test various features
9. Run npm run coverage
10. Verify all tests pass
11. Verify coverage results are above 80% and include server side code
