Pull request overview
This PR introduces the initial backend implementation for a ZUS (Polish Social Insurance Institution) accident reporting assistant. The backend uses FastAPI to provide a conversational API that helps users fill out accident report forms through natural language interaction, powered by Google's Gemini AI model via LangChain.
Key Changes
- FastAPI-based REST API with a conversational assistant endpoint for accident report data collection
- Integration with Google Gemini AI for natural language understanding and structured data extraction
- Pydantic models for type-safe case state management and API contracts

The API key is exposed in the environment variable without any validation. Consider adding a check at application startup to ensure GOOGLE_API_KEY is set, and fail fast with a clear error message if it's missing. This helps developers identify configuration issues early.
