Replace 4-radio-button filter with PrimeNG-style accordion (2 tabs: Flight Number, Route). Add swap button between departure/arrival in route filter, clear button on flight number input, time selector in route filter, flight number validation with error tooltip. Add SearchHistory component below filter, Breadcrumbs in page header, FeedbackButton stub, ScrollUpButton for scroll-to-top. SeoHead already wired on start page route. All tests updated to match new accordion structure.
