Adds a dedicated non-root user and switches to it before CMD. Verified the container runs as a non-root uid. Closes #7

chore: run container as non-root user
Build and publish container / build (pull_request) Successful in 9m17s
Details
5231b277d0 
Create a dedicated appuser/appuser system user and group, ensure the
copied application file is owned by it, and switch to that user with
USER before CMD. EXPOSE 110 25 is unchanged; ports are published via the
host -p mapping, so binding them as non-root works in the default Docker
network namespace without CAP_NET_BIND_SERVICE.

Fixes #7
