## Summary
- Fix E2E login test flakiness by using `click()` auto-waiting instead
of `isVisible()` check
- The login form shows a loader while GraphQL data loads. The previous
`isVisible()` check returned immediately (no waiting) and would fail
while the loader was showing
- Using `click()` which has built-in auto-waiting for elements to be
visible and actionable fixes this
## Test plan
- E2E tests should pass more reliably in CI
- Login setup test should no longer timeout waiting for the email field
