Add chams

- Hook IVModelRender::DrawModelExecute (VEngineModel016 slot 19) and force
  models/debug/debugwhite for NPC models, identified by
  ModelRenderInfo_t::entity_index.
- Two passes: MATERIAL_VAR_IGNOREZ through walls, then normal depth, with
  IMaterial::ColorModulate for the configured colour; restore the shared
  material's flag/colour afterwards.
- Material lookup via the IMaterialSystem list, FindMaterial fallback.
- New Chams feature/card with Through walls and colour; [chams] config.
- Remove the temporary ammo/projectile/fuse diagnostics.
