Add Chrome installation for Kaleido v1 support

Kaleido v1+ requires Chrome for image rendering. Add automatic
Chrome installation to setup process:

- Update Makefile to run kaleido_get_chrome after uv sync
- Update GitHub Actions workflow to install Chrome
- Update pyproject.toml to note Kaleido v1+ requirement
- Update requirements.txt

This ensures Plotly static image export works with Kaleido v1.
