Add emissive material support and ocean/landscape commands 

New MCP commands:
- set_actor_emissive_material: Apply glowing materials for sun, lights, screens
- spawn_ocean: Create WaterBodyOcean actor (requires Water plugin)
- set_ocean_waves: Configure Gerstner wave parameters
- create_landscape: Add minimal landscape for Water plugin support

Improvements:
- SceneCapture2D now renders atmosphere with correct ShowFlags
- DirectionalLight configured as atmosphere sun (SetAtmosphereSunLight)
- Added Water and Landscape module dependencies
