* 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.
Rework the nftables index page to make table, chain, and set management clearer. Move table actions next to the table selector, split chains and sets into tabs, use checked tables with standard select/invert controls for bulk deletes, move Add Rule into the Actions column, and replace nested rule tables with tag-based row layout.
