test(energy-cost): pin local_now in future-window summarize test

Browse Source 
test_future_window_counts_0_days relied on the real wall-clock date and assumed
7/1→8/1 2026 was entirely in the future; once that range started elapsing the
window counted fixed-fee days and the assertion failed. Pin local_now to
June 25 2026 (as the sibling window tests already do) so the case stays
deterministic.
