Added a basic login test and also added 2 small variables to dev .env file

Small test just to see if you wish to continue this way of me writing tests in this shape and form. you can run them locally with php artisan dusk:chrome-driver --detect, run it with ./vendor/laravel/dusk/bin/chromedriver-mac-arm --port=9515  then run tests with php artisan dusk
