- Add `password_plain` method to all `User` records created by FactoryBot to access the plain password for reuse to avoid variable spaming.
- Enable Capybara system test meta attribute `:authenticate` to handle a user as lambda return value which will be used for authentication instead of default `master@example.com`.
