Adapt the portfolio CLI test to project's reduced-order schema

Merge interaction between algebra-fixes and kinematic-order: algebra-fixes
made `symgcad project` report exactly the projection `solve` lifts, so
with a homogeneous anchor its `order` is the reduced order (anchor
removed) and the original lifting order moves to
`homogeneous.original_order`. kinematic-order's CLI test compared the
project `order` with the portfolio's full lifting order. The test now
compares the portfolio order with `homogeneous.original_order` (and the
reduced `order` with that order minus the chosen anchor) when the
projection is homogeneous; `order` output is unchanged. USAGE.md notes
where the chosen order appears in `project` output.
