fix(docker): resolve proxy pool configuration not loading in Docker deployment

Problem:
Docker uses 'uvicorn app:app' command which skips the if __name__ == '__main__'
block, causing load_dotenv() never executed and PROXY_URLS from .env not loaded.

Solution:
Move load_dotenv() to module level in app.py to ensure .env is loaded for all
startup methods (python app.py, uvicorn app:app, docker-compose).

Changes:
- Add module-level load_dotenv() in app.py
- Update Dockerfile version 1.0.4 -> 1.0.5
- Improve audio content display UI
- Add docs/ and scripts/ to .gitignore
