- Telegram: Procesar caption de fotos y videos con botones de traducción
- Discord: Ignorar mensajes vacíos (solo attachments sin texto)
- Si no hay caption/texto, los bots no procesan nada
- Si hay caption/texto, se traduce normalmente

Cambios:

- discord_bot.php: Agregar validación de texto vacío
- handleTelegramMessage: Ignorar textos vacíos
- handleAutoTranslationWithButtons: Ignorar textos vacíos
