- Text/interactive/button messages → NormalBot only, never escalates to AI
- Image/audio/video/document → AiBot.processMedia() if ai_for_media enabled,
else falls back to category greeting menu
- AiBot.processMedia() uses permission_type context so AI acknowledges uploads
for perm 3 and redirects others to their menu
- WpWebhook.handleMedia now calls BotRouter so the bot responds to media
- Admin UI: checkbox toggle "Procesar imágenes y archivos con IA" in AI tab
- categoryMenuFallback() extracted in BotRouter as shared helper

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.
