Add CasaExample FBX, update materials & packages

Add a new House asset (Assets/Game/House/CasaExample.fbx) with corresponding meta and folder metadata. Adjust World Canvas material (removed _SPECULAR_COLOR, disabled SHADOWCASTER pass, enabled XR motion vectors flag) and update Save Camera RenderTexture serialized settings. Update SampleScene LFS entry and bump Unity package versions in Packages/manifest.json (several dependency version updates). Also update ProjectSettings (project asset/hash and ProjectVersion to 6000.3.8f1).
