build(sweeps): migrate to uv (from pyenv in CI)

[kelu-wandb]

• Use uv in both dev flow and CI.
• Merge requirements.test.txt into requiremewnts.dev.txt.
• Don't bother with migrating to pyproject.toml because refactoring setup.py would be bigger change.

interesting, could we skip the uv install phase if we used the right orb?

let me revisit after this stack, so the tests we run have fewer resource requirements. :)
