feat(VocabPracticeDialog, VocabCourseView): implement event dispatch for hard vocabulary changes
- Added event dispatching for 'yourpart:hardvocab:changed' in both VocabPracticeDialog and VocabCourseView components to notify changes in hard vocabulary items.
- Implemented event handling in VocabCourseView to refresh the hard vocabulary list when the event is triggered, ensuring UI consistency across components.
- Included error handling for environments that do not support CustomEvent, enhancing robustness.
