When users send image files (PNG/JPG/WEBP/GIF) as Telegram documents rather than photos, the gateway rejected them with 'Unsupported document type'. This patch adds image format detection in the document handler, routing them through the existing image cache for vision tool access.

Problem
When users send image files (PNG, JPG, WEBP, GIF) as Telegram documents (file attachments) rather than as photos, the gateway rejects them with "Unsupported document type" because the image extensions are not in
SUPPORTED_DOCUMENT_TYPES.Solution
Add image format detection in the
elif msg.document:branch of_handle_media_message, routing.png/.jpg/.jpeg/.webp/.giffiles through the existingcache_image_from_bytespipeline — the same path used for native Telegram photos.Testing
