This PR renames the --service-log-file flag to --log-file for better CLI standards compliance. The change is consistently applied across gateway and relay systemd installation commands, along with their error messages.

• Renamed flag from service-log-file to log-file in gateway systemd install and relay systemd install commands
• Updated all error messages and help text to reference the new flag name
• Updated validation error message in systemd.go utility

The changes are straightforward, consistent, and maintain backward compatibility since this is a flag rename (users will simply need to use the new flag name).

• The changes are purely cosmetic renaming of a CLI flag from service-log-file to log-file. All references have been consistently updated across flag definitions, error messages, and validation logic. No functional logic was changed, and the refactoring improves CLI standards compliance.
