Update scenes, lighting and glass materials

Heavy authoring pass on The Room scene plus lighting/render tuning across
scenes: Lobby gets lower ambient/reflection intensity, softer shadow
strength and a baked lighting data asset; Main and Test Map drop their
lighting data/settings links. Replace the living-room Glass materials with
reworked versions under Assets/Materials, update BrightDaySettings, and set
hunterCount to 0 in Main.
