feat: add JSONL trade persistence + separate MTF deploy pipeline

- mtf_bot: ExecutionManager saves entry/exit records to
  data/trade_history/mtf_{symbol}.jsonl on every close
- Jenkinsfile: split MTF_CHANGED from BOT_CHANGED so mtf_bot.py-only
  changes restart mtf-bot service without touching cointrader
- docker-compose: mount ./data:/app/data on mtf-bot for persistence
