feat(dashboard): metal and glow looks in the UGC and zone 3D views

NifFile::ShaderLookFor knows Polished Metal (98), Brushed Steel (99) and
LEGO-Emissive (53). The UGC mesh route sends each mesh's look (from its
multishader tag), and the UGC 3D view draws metal as reflective and glow
unlit. The zone views draw LEGO-Emissive objects going to their vertex
color by its alpha, as the shader does.
