Recipe Balancer

Editor screen now runs as a client-side container screen (all three versions)

• The recipe editor is backed by a zero-slot, client-only menu so JEI treats it as a container screen.
• JEI ingredient/bookmark panels now avoid the two icon columns through declared extra areas instead of an inflated GUI width.
• R / U / A lookup on the editor's slots goes through JEI's container handler (the global handler stays as a fallback).
• No menu type is registered and no container packets are sent: the mod stays fully client-side, works on servers without it, and the editor never sends slot clicks or container-close packets.
