v8.2.1: Refactor server IP handling, update metric timestamp logic, and improve service configuration error handling

- Extracted `server_ip` for consistent use across server creation workflows.
- Replaced `datetime.now()` with `datetime.utcnow()` for metric timestamp standardization.
- Enhanced exception handling and logging in service configuration to improve debuggability.
