Create: Improve

Added the Batch Mechanical Crafter, a variant supporting batch crafting that allows each slot to hold a full stack of items to craft simultaneously and holds overflowing packages for subsequent batches when paired with the new Batch Repackager. The Batch Repackager processes batch crafting packages into a compatible format for the crafter, handles multiple packages when raw material quantities exceed a single package's capacity, processes multiple recipes sequentially, and ensures outputs are always integer multiples of the materials required for a single craft. Additionally, a Demand Request Mode toggle has been added to the Factory Panel's recipe mode (visible only when connected), which treats configured recipes as single-craft minimums and attempts to request all required materials at once to fill resource deficits, or sends the maximum available batches if the network's supply is limited. Fixed a server-side issue caused by mixing in client-only classes.
