Claude e256fca772 perf: shared Z inversion for GLV table pairs — saves one full inversion

pOdd and pLamOdd always have identical Z coordinates (the GLV
endomorphism λ(X,Y,Z) = (β·X, Y, Z) preserves Z). Previously we
called batchToAffine separately for each table, paying two full field
inversions (~270 field ops each). Now batchToAffinePair uses a single
batch inversion and reuses the Z⁻¹ values for both tables.

Saves ~270 field ops per mul/mulDoubleG call (~12% of ECDH cost).
