Added real server-authoritative smelting for Furnace on a Stick, with a faster enhanced tier and safe return of unfinished stacks.

Added portable workstation and connected Ancient Storage advancement milestones.

Added nearby Ancient Storage archive networking, stack compaction, deterministic sorting, and quick archive transfer.
