Keep the job completion filters alongside the other scheduling fields

started__* and completed__* are two halves of the same time range, so
splitting them across the Scheduling and Execution field sets made a run
window awkward to filter. Execution now holds only execution_time, and the
grouping matches JobSchedulingPanel on the detail view.
