StillHammer 5cef0e25b0 fix: UIModule button interaction + JsonDataNode array children support 
- Fix JsonDataNode::getChildReadOnly() to handle JSON array access by numeric index
- Fix test_ui_showcase to use JSON array for children (matching test_single_button pattern)
- Add visual test files: test_single_button, test_ui_showcase, test_sprite_debug
- Clean up debug logging from SpritePass, SceneCollector, UIButton, BgfxDevice

The root cause was that UITree couldn't access array children in JSON layouts.
UIButton hover/click now works correctly in both test files.

/**
* Visual Test: Full Stack Interactive Demo
*
* Demonstrates complete integration of:
* - BgfxRenderer (2D rendering)
* - UIModule (widgets)
* - InputModule (mouse + keyboard)
* - Game logic responding to UI events
*
* Controls:
* - Mouse: Click buttons, drag sliders
* - Keyboard: Type in text input, press Space to spawn sprites
* - ESC: Exit
*
* Build modes:
* - USE_STATIC_BGFX: Link BgfxRenderer statically (required on Windows)
* - Default: Load BgfxRenderer as DLL (works on Linux/Mac)
