The vehicle detail page had no error handling: a failed /vehicles/:id (404 or
network) rendered a broken header (" ()") with no retry, while only the
categories sub-page had a proper error block. Now a failed load shows a
not-found vs. generic-error alert with retry (mirroring the category page), and
404s skip retries so the state appears immediately. The back button now uses
the router history and falls back to /dashboard/search on deep links instead of
window.history.back() leaving the site.
