Display schema node properties

### Which Data Mapper Version are you using ?

v2

### Describe the Bug with repro steps

The current Data Mapper does not provide sufficient information on schema nodes, such as:

- Cardinality (e.g., unbounded, minOccurs, maxOccurs)
- String restrictions (e.g., maximum/minimum length constraints)

These properties are crucial for users to understand schema structure and constraints while mapping data. Customers require more visibility into node properties, similar to what was available with Properties panel in BizTalk that that displays metadata for each node, including constraints, data types, and allowed values

### Screenshots or Videos

Solution:

Contextual metadata surfacing for selected nodes and more intuitive ways to view constraints without cluttering the UI

### Version
