LANTERN purge B1: delete the automation chain (Harvester/Conveyor/Fabricator)

Deletes the M7 production systems, automation components/math, authoring, 3
machine prefabs, and 6 test files (-43 tests, 459 green). Trims the automation
paths out of BaseRestoreSystem/SaveStructureScan/BuildPlaceSystem/BuildSendSystem/
HudSystem/HudTheme/StructureCatalogAuthoring/Tuning. RuntimePlacedTag (save
marker, a keeper) re-homed into StructureComponents.cs. StructureType byte codes
stay reserved.
