Fix menu.sh to work offline with local backup

Remove network_ok check in menu.sh to allow running offline.
The run_script function will automatically:
1. Try to download from GitHub (if online)
2. Fall back to local backup (if offline or rate limited)

This allows users to run menu.sh for configuration changes
even when completely offline, as requested in issue #2771.
