* Note: Track saved nftables configuration changes with Apache-style config/apply timestamp flags, expose the standard restart.cgi header action for themes, and use it as the single apply endpoint. The button expands to “Apply Changes” when saved rules need applying, while the existing Apply Configuration action now routes through restart.cgi and clears the pending state after a successful apply.
