fix(rendering): add warnings for silent texture fallbacks

Browse source 
M2 particle/ribbon/batch, terrain layer, and WMO material texture
resolution paths were silently falling back to white textures when
indices were out of range — making missing texture issues hard to
diagnose. Add LOG_WARNING at each silent failure point with model
name, index details, and array sizes.
