fix(properties): name AEC / proxy objects instead of "Unknown"

Selecting a proxy object we render from its cached graphics (an AEC
Wall/Door/Window and the like) showed "Unknown" as its type. The entity
now carries its real DXF class name from the CLASSES section (acadrust
bump), so surface it: ui_name_or_class title-cases the class ("AEC_WALL"
→ "Aec Wall") for the properties Type row and the status-bar label, and
still says "Unknown" only when the class truly can't be named.
