Add The Room scene with living room environment, use it as the match scene

New The Room scene built from the Barking_Dog living room asset: prefab
variants under Assets/Prefabs/3D Living Room, an Environment Light prefab and
baked lighting settings. Point MatchManager at The Room (was Test Map) and
swap it into the build settings scene list. Floor_Wood material and the
living room meta files are reserialized by the URP/Unity importer. Main.unity
also carries the inspector-pinned defaults of the orbit-zoom and hunter-count
fields (matching the C# defaults, no behavior change).
