feat: add WALL_CABLE electrical type and room outlet/switch count stats

Add wall cable item — a bare cable exit from the wall for direct
consumer connection without an outlet. Includes 2D symbol (circle +
cable stub), 3D mesh (round plate + protruding cable), and palette entry.

Also add outlet and switch count metrics to the room info section in
the properties panel.
