Refactor LibreTranslate environment variable names across configuration files

- Updated environment variable names in .env.example, Caddyfile, and docker-compose.yml for consistency and clarity.
- Adjusted the final report script to reflect the new variable names, ensuring accurate output.
- Enhanced the script for generating secrets to accommodate the updated variable names, improving maintainability.
