InteractiveBox now provides a dedicated matrix tab to directly input or edit 4×4 matrices. This mode coexists with the existing field-based editor (Position/Rotation/Scale), and switching between the two keeps values synchronized in both directions.

Developer notes

• Usage: keep using panel_widget="InteractiveBox" in the XML.
• Requirements: the proxy must expose Position, Rotation, and Scale properties; when present, the Matrix tab appears.
• Synchronization: matrix and PRS are converted both ways.
