fix: preserve date picker state when switching back from unlimited (#1904)

When switching to unlimited and back to an accrual method, the custom
reset date picker wasn't showing because the useEffect aggressively
cleared resetDateType. Now the effect returns early for unlimited,
preserving form state so the date picker restores on switch-back.
