Add unit tests for manager module functionality in ModuleReference

Added tests for:
- isManagerModuleExpression() detection with null check
- extractManagerModuleInfo() for Catalogs (Справочники)
- extractManagerModuleInfo() for Documents (Документы)
- extractManagerModuleInfo() for InformationRegisters (РегистрыСведений)
- English syntax support (Catalogs.Nomenclature)
- Non-manager module expressions returning false/empty
