It is no longer about reprocessing: any recipe with several output groups is
subject to it, and the plant is only the building that happens to have one
(REQ-MAT-OUTPUT-GROUP). REQ-LOCK-REPROCESSING-POOL becomes REQ-LOCK-OUTPUT-POOL.
Four citations, all in docs -- no code cites it.
Also corrects a line REQ-LOCK-IMPLICIT still carried from before smelters had a
recipe control: their recipes are not "never shown in any UI dropdown" any more,
they are simply never gated, so the dialog offers all of them.
