Several components still read `flight.operatingBy.carrier` directly.
The API actually returns `{scheduled, actual}` — I kept `.carrier` on
IOperatingBy as a deprecated alias during the refactor, so nothing
fails typechecking, but at runtime the lookup is always undefined,
which silently disabled the Registration, Flight-status and
Operated-by UIs (the Reg button did nothing on click, the status
visibility check always returned false).
Swap the affected sites — RegistrationButton, FlightStatusButton, the
canRegister / canViewFlightStatus visibility helpers, and the
'Operated by' block in OnlineBoardDetailsPage — to use the
operatingCarrier() helper that reads actual/scheduled/legacy in turn.
