Remove enhancement check from observer - let function handle it

The observer was checking if enhancement exists before calling the function,
which prevented it from detecting when a different item was selected.

Now the observer always calls enhanceInventoryItem() when panel is visible,
and the function itself checks if the panel needs to be replaced based on assetid.
