fd508e4a68 fix: UITextInput focus and keyboard input - hitTest + dispatch handlers 
Fixed three critical bugs preventing UITextInput from working:

1. **hitTest() missing textinput handler**: The hit test function only checked
   for button, slider, and checkbox types. Clicks on text input fields were
   never detected.

   FIX: Added textinput case to hitTest() in UIContext.cpp

2. **dispatchMouseButton() missing textinput handler**: Even if hit test worked,
   mouse button events were not dispatched to text input widgets.

   FIX: Added textinput case to dispatchMouseButton() in UIContext.cpp

3. **Keyboard event collision**: SDL_KEYDOWN was publishing events for printable
   characters with char=0, which were rejected by UITextInput. Printable chars
   should only come from SDL_TEXTINPUT.

   FIX: Only publish SDL_KEYDOWN for special keys (Backspace, Delete, arrows, etc.)
   Printable characters come exclusively from SDL_TEXTINPUT events.

Changes:
- UIContext.cpp: Added textinput handlers to hitTest() and dispatchMouseButton()
- UITextInput.cpp: Added debug logging for gainFocus() and render()
- UIModule.cpp: Added debug logging for widget clicks
- test_ui_showcase.cpp: Fixed keyboard event handling (KEYDOWN vs TEXTINPUT)

Tested: Text input now gains focus (border turns blue), accepts keyboard input,
and displays typed text correctly.

- test_29_ui_advanced.cpp - Tooltips on various widgets
- assets/ui/test_scroll.json - ScrollPanel layout
- assets/ui/test_tooltips.json - Tooltips layout

## Documentation

- docs/UI_MODULE_PHASE7_COMPLETE.md - Complete Phase 7 docs
- docs/PROMPT_UI_MODULE_PHASE6.md - Phase 6 & 7 prompt
