Match Angular details layout when no parent request is present

- Drop the duplicate FlightCard summary between the header and the route
  strip — Angular's details page shows the route strip directly under the
  board-details-header, with no 'SU 6272 Russia 15:30/15:22 ...' row.
- Keep the mini-list sidebar visible even when allFlights has only one
  entry; fall back to rendering the current flight as a single item,
  matching Angular's flights-details-list-flight behavior.
