feat: add Telegram bot for manual trade commands

- Added telegram_command_bot.py with slash commands (/buySOL, /sellBTC, etc)
- Docker compose setup with DNS configuration
- Sends trades as plain text to n8n webhook (same format as TradingView)
- Improved Telegram success message formatting
- Only responds to authorized chat ID (579304651)
- Commands: /buySOL, /sellSOL, /buyBTC, /sellBTC, /buyETH, /sellETH
