Users can now attach images in the web chat for Simba to analyze using Ollama's gemma3 vision model. Images are stored in Garage (S3-compatible) and displayed in chat history. Also fixes aerich migration config by extracting TORTOISE_CONFIG into a standalone config/db.py module, removing the stale aerich_config.py, and adding missing MODELS_STATE to migration 3.
