feat(properties): add 3D Visualization group + General Plot style/Hyperlink

Per the COMMON section of PROPERTIES.md. Insert a "3D Visualization" group
(Material, Shadow display) after General for every graphical object, and add
Plot style + Hyperlink rows to General. Material / plot style / shadow are
sourced from the entity's flags (ByLayer / ByBlock / custom); resolving a
custom material or plot-style handle to its name, and reading the hyperlink
from XDATA, are follow-ups that need document access.
