When picking an entity, show the context in the tree

[tudorache]

Requirement after the demo for iCAT users on 11.09.2024:

• When users are searching for an entity (e.g., subclass base inclusion, or base exclusions, or value sets), they need to understand where exactly that entity is found in the tree. We need a way to show the context of the search results in the tree, so that the user can select the appropriate class. Just seeing the entity name is not enough for selecting the right one.
