Add the initial 1.0.0 changelog, bump the package/application version,
and expose the release version through `pobsync --version`.
Cover the version output in the console entrypoint tests.
Run the Django control panel with Gunicorn instead of the development
runserver and serve static files through WhiteNoise.
Add restart policies, healthchecks, .env-driven production settings, and
a sample .env file for single-server deployments. Update the Docker
entrypoint to collect static assets and document the remote server
deployment and update flow in the README.
Add a Django admin-backed management layer for pobsync configs, runs,
snapshots, and schedules. Keep the existing CLI engine as the execution
source of truth, add import/run management commands, and provide SQLite
default plus optional MariaDB Docker Compose support.
