[UI] Shape matching

[bergos]

To render the UI, we need to define a logic for identifying matching shapes. This involves defining a matching logic that connects shapes with the data graph. One potential solution is to use SHACL targets. However, we may also consider and review other approaches, such as looking up the shape via the sh:shape property, or property roles.

After matching shapes are identified, and more than one shape matches, an order/priority of the shapes must be determined or a merge logic must be applied.

Edit 2025-10-21: Added sh:shape property and property roles as possible other approaches.
