Add unsaved changes warning modal in Form Builder

- Implemented a modal to warn users about unsaved changes when navigating away from the form builder.
- Added computed properties and methods to manage unsaved changes state and navigation confirmation.
- Updated the form management page to include unsaved changes handling when creating new forms.
- Enhanced the form store to track unsaved changes status, ensuring better user experience and data integrity.
