MONKEY (visualfix): volumetric fog density follows the rendered clock

The dawn/weather density curve read WorldTime, the server clock, which stays at its noon default
offline, so a manual or capture time never got the dawn mist. It now reads the rendered minute
through grading's rendered_minute (the same rule as ac9a1ef3). Baselines move: volfog-dawn is
mistier (MAE 8.5), volfog-night is unchanged (0.07).
