refactor: Remove layer-related GridPoint properties, fix layer z-index

- Remove color, color_overlay, tilesprite, tile_overlay, uisprite from
  UIGridPoint - these are now accessed through named layers
- Keep only walkable and transparent as protected GridPoint properties
- Update isProtectedLayerName() to only protect walkable/transparent
- Fix default layer z-index to -1 (below entities) instead of 0
- Remove dead rendering code from GridChunk (layers handle rendering)
- Update cos_level.py demo to use explicit layer definitions
- Update UITestScene.cpp to use layer API instead of GridPoint properties

Part of #150 - Grid layer system migration
