refactor: major overhaul and cleanup of the build environment

- Removed `.env.sample` and improved `.env` handling
- Deleted `translate.py` and replaced it with `translate-md.py`
- Refactored `readme.yml` to enhance translation and tagging workflow
- Updated `.gitignore` with new exclusions
- Major restructuring of `Dockerfile`, including improved ENV variables and layout
- Extended `create-env.sh` with interactive prompts and validation
- Improved error handling and structure in `docker-compose-wrapper`
- Expanded `docker-compose.yml` with new environment variables and network settings
- Moved and updated `init.sh`, `.bashrc`, and other files to `files/` directory
- Added new scripts: `show-env.sh` for better diagnostics and `terminal-splash.txt` for enhanced display

These changes optimize the build environment for improved stability and flexibility.
