Fix chat UI position, font initialization, and input handling

- Move chat Y position from 200 to 50 to display correctly at top-left
- Fix font initialization to use lucasFont.createDefaultFont() instead of raw lucasFont
- Add fallback font (Tahoma) if Arial fails to load
- Use bindKey for T key binding for more reliable chat toggle
- Define key code constants with fallbacks for SDLK_* values
- Filter control characters from text input
- Add test message on resource load to verify chat is working
- Improve native chat disabling with proper function checks
