Subject: [PATCH] fix: AiBot returns null on API errors instead of hardcoded
 error string

Returning an error string caused the bot to send "Lo siento, tengo
problemas para procesar tu mensaje" to the user whenever OpenAI/Gemini
was unavailable or misconfigured. Now it returns null so BotRouter can
fall back to the category greeting menu instead of sending the error.
