Fix ClickHouse server startup - use background process not daemon

The --daemon flag wasn't working properly, causing connection failures.
Replace with background process (&) approach:

Changes:
- Run server in background with output redirect to log file
- Capture PID for debugging
- Add error handling to show logs if startup fails after 60s
- Remove problematic --daemon and -- syntax

Benefits:
- More reliable startup
- Better debugging with accessible logs
- Standard Unix background process approach
- Logs available on failure for troubleshooting

This should fix the "Connection refused (localhost:9000)" error.
