Update `kaleido` and migrate to `uv`

[j-adamczyk]

This issue suggested upgrading Kaleido to 1.x, which would fix a lot of dependencies. It was actually implemented in this PR moving NannyML to uv, but it was turned to stale and closed automatically. Why was that PR ignored? This now creates 2 issues + problems with dependencies, since Kaleido had problems with PyPI wheels pre-1.x (which now I run into).
