fix: missing headers on new arch (#6725)

## Summary
PR adding back headers removed in
#6537.
For some reason, locally they are not needed, probably to some different
setup or having the libraries set globally somewhere, but it caused
failures in Expensify:
https://github.com/Expensify/App/actions/runs/11857735322/job/33046828856.
They should be included since methods from them are used.
## Test plan
Not really, just run CIs probably.
