test: log in with the api rather than through the UI for most react tests

Ticket

infeng-671

Description

Previously for all our tests we logged in by navigating to the UI and logging in. It will be faster and have less code to just auto-login through the API and apply the cookie to the browser.

More stuff coming in user management with the next ticket, but this is a self-contained start.

Test Plan

ran manually and CI should pass.

this looks pretty good! i guess we didn't change user spec yet. maybe in the future we can use swagger codegen
