Replaces the right-anchored popover (which clips off the popup edge) with an inline panel that injects into the form below the password row. Trigger becomes a ✨ icon button (gold-bg). "save default" demoted to secondary link; single gold "use" CTA. Bundles label-casing polish (drop CAPS LOCK, gold required marker) since .label is shared.
