fix: UIModule button interaction + JsonDataNode array children support

Browse Source 
- 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.

* BgfxRenderer Complete Showcase

* Demonstrates ALL rendering features of BgfxRendererModule:
* - Sprites (static, animated, colored, layered, rotated, scaled)
* - Text (different sizes, colors, multi-line)
* - Particles (with life, velocity, size, additive blending)
* - Tilemap (simple grid with tile indices)
* - Debug primitives (lines, rectangles wireframe and filled)
* - Camera (orthographic projection, panning, zooming)
* - Clear color
*
* Controls:
* - Arrow keys: Move camera
* - +/-: Zoom in/out
* - SPACE: Spawn explosion particles
* - C: Cycle clear color
* - ESC: Exit

* - UIModule appelle render() sur chaque widget
* - UIButton::render() publie un sprite via IIO topic "render:sprite"
* - BgfxRenderer reçoit le sprite et le dessine
*
* 3. Les styles du bouton:
* - normal: état par défaut
* - hover: quand la souris est dessus
* - pressed: quand on clique
* - disabled: quand enabled=false
*
* 4. Les événements publiés par UIModule:
* - ui:hover - quand on entre/sort d'un widget
* - ui:click - quand on clique

/**
* UIModule Complete Showcase
*
* Demonstrates ALL widgets of UIModule:
* - UIPanel (containers, backgrounds)
* - UIButton (click actions, hover states)
* - UILabel (static text, different sizes)
* - UICheckbox (toggle states)
* - UISlider (horizontal values)
* - UITextInput (text entry)
* - UIProgressBar (animated progress)
* - UIScrollPanel (scrollable content)
*
* Uses BgfxRenderer for rendering.
* Uses manual SDL input converted to IIO messages.
*
* Controls:
* - Mouse: Interact with UI widgets
* - ESC: Exit
