Props: disable StudioRender hooks, fix m_clrRender offset

Hooking IStudioRender's draw/setter slots made matched props render the error
material and then crashed the material system ("debug/modelstats has bad
reference count 0 when being bound"). Keep the hook code for reference but do
not install it.

Fix the m_clrRender netvar resolution: the walk picked an embedded table entry
at offset 0, so the earlier entity writes stomped entity vtables. Only accept
offsets inside C_BaseEntity (0x20..0x2000), then write the prop colour there
for models/props entities. Restore white when disabled.
