Code Review
This pull request updates the layer color assignment logic in both the GUI (displayControls.cpp) and the web tile generator (tile_generator.cpp) to ensure that backside layers are assigned random colors and do not consume the standard frontside palette colors. A unit test was also added to verify this behavior. The reviewer suggested refactoring the test setup to use a loop with safety checks when retrieving layers, preventing potential segmentation faults if any layer is missing.
