feat: Refactors Docker setup to improve security and efficiency

Switches base image from Python to Alpine for a slimmer image and improved startup efficiency.

Uses a virtual environment for Python dependencies and adds a dedicated user for the application, enhancing security and environment isolation.

Introduces a new entrypoint script for better configuration of uWSGI server and updates Docker compose setup to include security options and resource limits. Removes old compose file in favor of a more secure configuration example.
