This PR fixes
sum_squarescanonicalization for affine expressions in objective.The old$|x|_2^2$ in the objective as a QP. Everything else fell through to the SOC epigraph reformulation, which causes the solver to actually minimize $|Ax + c|_2$ instead of $|Ax + c|_2^2$ for such expressions. This fix generalizes the QP path to handle the full affine case $|Ax + c|_2^2$ by expanding it analytically.
sum_squares_linonly handles the trivial case
