Angular renders the breadcrumb trail on its own row above the H1 title.
React had them in the same flex row with justify-content:space-between,
which squeezed the breadcrumb column and forced 'Главная / Онлайн-Табло'
to wrap onto two lines. Switch the header-right container to column
layout so breadcrumbs and title stack vertically regardless of width.
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.
Add blue background/hover styles to the search button matching Angular's
.color.blue button pattern. Fix page title width to calc(100% - 120px)
matching Angular layout. Conditionally render sticky-content wrapper
to avoid empty DOM nodes.
Port the Angular page-layout wrapper and flights-page-tabs navigation
to React, preserving identical DOM structure and CSS class names so
global SCSS styles apply without modification.
