Enhance Form Management with Dynamic Configuration Updates

- Added a new watcher in `OpenCompleteForm.vue` to monitor changes to the form prop and update the form manager accordingly, ensuring that the form manager reflects the latest configuration.
- Introduced an `updateConfig` method in `useFormManager.js` to handle updates to the form configuration, resetting the form state and reinitializing with the new config. This improves the flexibility and responsiveness of the form management system.

These changes aim to enhance the user experience by ensuring that form updates are seamlessly integrated into the form management workflow, allowing for more dynamic interactions.
