This PR updates the Lumir AI backend to support processing multiple images.

Previously, sending a new image would overwrite the last one in the bot's memory. Now, images are appended to a list.

The ###topdf### command has been upgraded to convert all accumulated images into a single multi-page PDF.

Legacy commands like ###passport###, ###ocr###, and ###compress### have been updated to operate on the most recently sent image, preserving backward compatibility.

- Update `backend/lumir/engine.py` to store received images in a list instead of overwriting the previous one.
- Update `backend/lumir/utilities.py` to replace `convert_image_to_pdf` with `convert_images_to_pdf`, which combines multiple images into a single PDF using Pillow.
- Update legacy commands (Passport, OCR, Compress) to use the last received image.
- Clear image memory after processing PDF, Passport, OCR, or Compression commands.
- Update AI response to indicate the number of images received.
