Fix FastAPI worker crash and improve container stability#17
Conversation
This commit addresses the issue where worker processes would die upon startup in a containerized environment (e.g., Kubernetes). 1. Switched from Alpine-based to Debian-based slim Python image to improve compatibility with C extensions and provide a more stable runtime environment. 2. Refactored app/main.py to use FastAPI's lifespan event handler for initializing the MongoClient. This ensures each worker process creates its own connection pool after forking, preventing issues with shared file descriptors. 3. Added build-essential to the Dockerfile to ensure that dependencies can be compiled if necessary. Co-authored-by: nmagee <699798+nmagee@users.noreply.github.com>

The FastAPI application was crashing when run with multiple workers in a containerized environment (Alpine Linux). This was primarily due to the MongoDB client being initialized at the module level (before process forking) and potential compatibility issues between Alpine's musl libc and Python C extensions.
I have:
