Update docker-compose.yaml and config.json for improved performance and configuration adjustments

- Bump Docker image version from 1.2.0 to 1.4.0 for enhanced functionality.
- Modify config.json to change trail_head_blocks from 0 to 3, adjust snapshot_sync sleep from 3 to 1.5 seconds, and increase batch_size from 1800 to 10000, while adding sync_period of 10 seconds for better synchronization efficiency.
