[TIMtechnology]

Closing without merge because the dependency lock state is incomplete. This PR changes backend/requirements.txt to FastAPI 0.140.12, while requirements.lock and requirements-dev.lock remain on 0.140.7. Production installs the runtime lock and CI installs the development lock, so the green checks did not actually exercise 0.140.12. Please recreate the update with both lock files regenerated and the full release gate run.
