Accept feasible non-optimal OPF solutions instead of computing an IIS

Large SOC OPF instances often end with barrier status SUBOPTIMAL: a
feasible primal point exists but the convergence tolerances were not
met. The previous check treated every status != OPTIMAL as infeasible
and called compute_conflict!, which raises Gurobi error 10015 ("Cannot
compute IIS on a feasible model"), killing the Julia process and
failing the grid run.

Now the solution is used whenever the solver proves optimality or
reports a feasible primal point; the IIS conflict is only computed
when there is genuinely no primal solution. The SOC tightness check
remains restricted to proven optima.
