### What problem does this PR solve? Problem Summary: Oceanbase container sometimes start failed. <img width="653" alt="image" src="https://github.com/user-attachments/assets/d95c66cf-7e04-4179-a565-9b9dd8b87128" /> We do two things: 1. Print last 100 lines docker logs of unhealthy container for debugging 2. Upgrade Oceanbase docker image to the newest `4.2.1-lts`, since it is 7 months newer than `4.2.1`, more stable
