Implement OS detection and enhance disk monitoring in ServerMonitor

- Added OS detection functionality to the ServerMonitor class, allowing for tailored disk usage and uptime calculations based on the operating system (macOS or Ubuntu).
- Introduced methods for retrieving disk usage and I/O statistics specific to the detected OS.
- Updated the process status check to return uptime information for monitored processes.
- Enhanced the status message format to include disk space emojis and process uptime details.
- Updated tests to reflect changes in process status checks and output formatting.
