Migración de dbgtxt a SDL_TTF + conversión de textos a mixed case

Sistema de texto:
- Reemplazado dbgtxt.cpp (bitmap 8x8) por TextRenderer (SDL_TTF)
- Creado source/text/ con TextRenderer class
- Añadidas fuentes TrueType en data/fonts/
- Implementados dos TextRenderer (display + debug) con escalado dinámico
- Constantes configurables: TEXT_FONT_PATH, TEXT_BASE_SIZE, TEXT_ANTIALIASING

Correcciones de centrado:
- Reemplazado text.length() * 8 por text_renderer_.getTextWidth() en ~25 lugares
- Texto de tecla F ahora se centra correctamente
- Texto de modo (Demo/Logo/Lite) fijo en tercera fila del HUD debug
- Implementado espaciado dinámico con getTextHeight()

Conversión a mixed case:
- ~26 textos de display cambiados de ALL CAPS a mixed case
- 15 nombres de temas en theme_manager.cpp convertidos a mixed case
- Ejemplos: "FPS" → "fps", "MODO FISICA" → "Modo Física", "DEMO MODE ON" → "Modo Demo: On"
- Temas: "SUNSET" → "Sunset", "OCEANO" → "Océano", etc.
