Refactor VNDB Telegram Bot

- Remove config.py and integrate environment variable handling directly in docker-compose.yml.
- Delete detailed_handlers.py and replace with simplified command handlers.
- Update requirements.txt to use aiogram and httpx instead of python-telegram-bot and requests.
- Remove test_bot.py and utils.py, consolidating functionality into new VNDBClient class.
- Implement VNDBClient for API interactions, simplifying query methods for visual novels, characters, and releases.
- Clean up docker-compose.yml for improved readability and maintainability.
