chore: enforce uv lockfile consistency in CI and pre-commit (#1398)

* chore: enforce uv lockfile consistency in CI and pre-commit

  Add --locked flag to uv sync in CI to fail if uv.lock is out of sync,
  and add the uv-lock pre-commit hook to automatically keep uv.lock
  up to date when pyproject.toml changes.

* chore: add missing --locked calls
