feat(ui/ci): add unofficial languages masking, OS lang detection, and optimize CI with uv

- Support Italian, Vietnamese, and Norwegian target languages with a UI warning and a masking language selector dropdown

- Implement automatic OS language detection on startup

- Fix JobConfig keyword argument mismatch in review retranslation

- Reformat all UI locales to avoid spacing/line-wrapping issues

- Integrate uv (setup-uv@v5) in build/release workflows and upgrade actions versions (checkout@v6, download-artifact@v8, upload-artifact@v7)

- Add uv auto-detection with fallback in build.py for local dependencies setup
