Description
When making https://github.com/openedx/frontend-app-authn/pull/1497 I ran into the following error
● Validation Error:
Module ts-jest in the transform option was not found.
<rootDir> is: /home/bsmith/code/frontend-app-authn
Configuration Documentation:
https://jestjs.io/docs/configuration
I was able to work around it by running npm install ts-jest --save-dev directly in the MFE, but it seems like we shouldn't need to do that.

Research direction
Start by reproducing the Jest validation error in the frontend-app-authn micro-frontend, using the transform configuration and the reported ts-jest workaround as the entry points. Trace how frontend-build supplies or expects this dependency, then verify that the affected MFE no longer needs a direct npm install and that Jest validation passes.
