config: add Docker-compatible env backend configuration example

- Add config.example.toml showing env backend setup for Docker
- Update docker-compose.yml with TRAKT credentials as environment variables
- This configuration resolves file permission issues in Docker environments
- Environment variables are more secure and Docker-native for production
