Subject: [PATCH] refactor: simplify panel state management and enhance
 template syntax in content metadata component

- Replaced inline conditional checks with dedicated methods for panel expansion and editing states.
- Updated template syntax to improve readability and maintainability using @if syntax.
- Removed unused CommonModule import and added AsyncPipe for better performance.
