35973: ResetCrewTimers — per-frame crew action-countdown walk
Called from GameEntry each frame: walk all 8 actor records, decrement every non-parked action countdown (IX+0), and fire the queued action on the 1->0 transition — DispatchCrewAction then jumps through CrewActionDispatch into the per-state handlers (36034 move/idle, 36101 duct transit, 36150 remove grille, ...).
