2490: Refactor dialog actions to run within WriteAction context

Updated dialog action methods from `onOK` to `onWriteActionOK` and ensured execution through a centralized `executeOnOk` method. This improves thread safety by enforcing operations within the IDE's `WriteAction` context. Also added handling for exceptions during execution and support for dumb mode in `NewModuleFileGroup`.
