feat(properties): fill solid-history + viewport clipped rows

Bump acadrust to ef0e231 (region/body history handle + viewport clip
boundary now stored) and populate the rows the builders left blank:

- Solid3D / Body "Show History": derived from the history handle's
  presence (there is no separate stored bool — the DWG carries only the
  H 350 history link).
- Body "History": the history handle, matching how Solid3D already shows
  it.
- Viewport "Clipped": Yes when the clip-boundary handle is non-NULL.

Hatch Origin X/Y and Boundary retention stay blank by design: they are
not part of the persisted AcDbHatch record in DWG or DXF (retention is a
BHATCH command setting), so there is nothing to read.
