refactor(src/utils): improve error handling and messaging in system utilitiesNew Features

- None

Enhancements- Added detailed error reporting with exit codes for privilege escalation, initramfs rebuild, service management, and session termination
- Implemented graceful handling of permission‑setting failures with proper logging
- Enhanced error messages for systemctl and loginctl commands, providing clearer diagnostics

Bug Fixes- Fixed incomplete error propagation in status matching, now reports actual exit codes or underlying errors
