Add estimated-time note after leg route and accordion icons

- Move the '* Время прилета...' note from the footer to right after the
  LegRoute, matching Angular's position between the route strip and the
  Детали рейса accordion.
- Add inline SVG icons for each FlightDetailsAccordion row
  (Регистрация, Посадка, Высадка, Воздушное судно, Питание, Услуги) in
  blue to mirror Angular's sprite-based icons.
