L7b: add a cash term to the Cobb–Douglas budget

The boxed budget was an equality with no cash, yet an empty basket
holds the floors plus cash. The budget now reads
sum_i n_i S_i(t) + cash(t) = W_P(t) with cash(t) >= 0, cash outside
the utility. One derivation line sets cash to zero when the basket is
not empty, so the empty-basket rule follows from the model and matches
allocate_cobb_douglas, which returns (shares, cash). Lecture, deck
(slides 17 and 18), and the package docstring updated; no code change.
