AI Summary: This issue requires developing a backend feature to process uploaded PDF files. It involves extracting content, generating embeddings using Azure OpenAI, storing these embeddings in a local FAISS vector index, and creating corresponding JSON metadata for each PDF. All Azure OpenAI configuration variables must be stored in a `.env` file, and the solution should be efficient for handling multiple and large PDF files, with comprehensive unit tests.
