Add APP_VERSION handling in Dockerfile and config.py

Updated the Dockerfile to include an ARG and ENV for APP_VERSION, allowing for version specification during build time. Modified config.py to set a default APP_VERSION, which can be overridden by the environment, enhancing flexibility for deployment and runtime configuration.
