The port manager's 'Show advanced fields' control was a raw <input type=
checkbox> + <span>, out of step with the modern pill switch the Services tab
uses for its Advanced toggle. Swap the markup to the shared .lp-ui-advanced-
toggle (track + thumb) structure — defined in services.css, which is loaded
globally — keeping .port-manager-show-advanced on the input for the JS hook.
Drop the now-dead .port-manager-advanced-toggle CSS.
