feat(install): Enhance systemd service setup guidance

- Improve post-service setup output with clear sections and details.
- Display service name, file paths (service unit, config), and working directory.
- Provide a list of common systemd service management commands.
- Add validation to ensure the config file exists before creating the service.
- Improve service start logic: check for successful start and report current running status.
- Include the service's current running status and a command to edit the config file in the final installation summary.
- Refine the manual test instructions in the summary for clarity.
