Add explicit controller definition requirement for APIs

Updated API creation to require an explicit controller definition. This change has been reflected in the ChillMainExtension and ChillPersonExtension files. Also, it has introduced a new exception, the InvalidCrudConfiguration, which will be thrown when a new API or CRUD is created without this explicit controller definition.
