	ContentAdminUi — the dock-widget UI for the no-code content builder. A thin layer over
	ContentAdmin (the logic): it renders an Items section and a Gatherables section, each with a
	"create" row and one editable panel per entry (field rows + Delete). Edits route through the
	applySet / applyCreate / applyDelete callbacks the plugin main supplies (which wrap the
	ContentAdmin call in a ChangeHistoryService recording, then refresh). Styling matches
	StatAdminUi / docs/design-language.md.
