Calibrate Measurement Scales in the Unified Viewer

The Unified Viewer includes a redesigned measurement panel aligned with Procore design standards. If a document lacks a scale bar or legend, users can perform manual calibration by selecting a known distance directly on the document and entering its real-world value.
