[Enchantement] - Item selector items should default to the item selected (in the entry)

Search for `Defias Rogue Wizard` and go to `Quest Item` or `Equip Template`


Upon checking the "..." the default value always should show me the existing one


Oh i forgot what item he's using (in the case if you want to see what item he's healding without going out of keira)

For our example we are using `1907` in this case a exact value and not a LIKE so it only shows the current one by default as below as an example


Reproduce the steps with `Defias Rogue Wizard`, then open `Quest Item` or `Equip Template` and inspect the item selector behavior. Trace the selector entry point for the existing item and verify that it defaults to the exact current value, such as item `1907`, rather than a LIKE search; done when the current item is shown by default.
