Unify all option panels through MTH_Layout engine

Add reusable MTH_Layout box/column layout engine (api/options-layout.lua) and route every option panel through it (shell, general, zButtons per-button config, zBar, chronometer, auto buy, profiles, credits, etc.) for consistent, auto-sizing layout. Restore realm gate. README note.
