Summary of Changes

This pull request improves the stability of the view by preventing potential null reference errors when accessing properties of $this->item.

In several locations, properties such as id, checked_out, and created_by were accessed directly from $this->item. In cases where $this->item is not initialized or unexpectedly null, this could trigger PHP warnings or runtime errors.

To address this, the code now uses PHP's null-safe operator (?->) and appropriate fallback values where necessary.

Reason for the Change

These changes ensure safer property access and prevent potential errors when $this->item is null or not fully initialized.

Using the null-safe operator improves code robustness without altering existing functionality.

Backward Compatibility

This change does not modify any business logic or introduce behavioral differences. It only improves defensive coding practices and error safety.

Testing Instructions

1. Navigate to the component view where these methods are executed.
2. Open both normal edit view and modal edit view.
3. Confirm that the toolbar loads correctly.
4. Verify no PHP warnings or errors appear when $this->item is not set.

Expected Result

The view behaves exactly as before but is now protected against null access errors.
