Refactor Docker Compose examples and documentation

- Updated README.md to include new example files for minimal and production configurations with detailed instructions.
- Added compose.production-alt.example.yml for an annotated production setup.
- Introduced new example files: compose.minimal.example.yml, compose.production.example.yml, nginx.example.conf, and traefik.example.yml for better clarity and usability.
- Removed outdated configuration files and consolidated documentation for OCR language support.
- Adjusted Nginx and Traefik configurations to reflect best practices and added necessary comments for user guidance.
- Minor formatting and consistency improvements across documentation files.
