ExpiredQuoteNotice

import ExpiredQuoteNotice from "@dertour/ui/components/common/ExpiredQuoteNotice/ExpiredQuoteNotice"

Prominent notice shown on an expired quote so the customer understands the quote is no longer valid (§2.2 "expired" condition). Render-only — the caller decides *whether* to show it via `isQuoteExpired`; this component only decides *how* it looks. The single source of the expired copy so it stays consistent and can be CMS-driven in one place.
