test: trash auth e2e tests have race condition on navigation (#15468)

### What

Two trash e2e tests for auth-enabled collections are flaky in CI:
"`Should properly disable auth fields in the trashed user edit view`"
and "`Should properly restore trashed user as draft`"

### Why

Race condition: both tests click a table row to navigate but don't wait
for navigation to complete before asserting on page elements. CI
environments can be slower, causing elements to not exist yet when the
assertions run.

### How

Added `await expect(page).toHaveURL(/\/users\/trash\/[a-f0-9]{24}$/)`
after row clicks to wait for navigation to complete before checking for
elements.
