Returns every stuck work item in a selection to the queue.

The dead-letter queue's select-all. The selection is explicit ids or a filter (stage, status, admission window); it is resolved to a concrete set and that set's size must equal `confirmCount`, otherwise the call is refused with 409 and the real count — so a filter is only ever acted on as the items the operator saw. Only DEAD and FAILED items qualify; an item a pass claimed in between is left alone and reported in the affected count.
