Refactored FruitBankConst and FruitBankConstClient to delegate PROD/DEV environment logic to AcEnv.IsProdDb, removing local state and events. Updated MGGRID_TODO.md with ADR reference. Added ADR 0002 documenting the migration of environment infrastructure (BaseUrl, env state, badge) to the framework. Updated settings.local.json with new doc/code read commands and improved build error reporting.
