Increase normal map Sobel strength and POM scale for character models

Browse source 
Hand-painted weapon/armor textures have baked-in lighting that produces
low-contrast gradients in the Sobel filter. Bump strength from 2.0 to
5.0 to extract visible surface detail. Also increase POM scale from
0.03 to 0.06 since character models are small with dense UVs where
the WMO-tuned 0.03 was barely perceptible.
