Extracts the 35-carrier logo path table from OperatorLogo into a shared
pure module (src/shared/operatorIcon.ts) so the mapping can be tested and
reused independently. Adds the 7-range SU flight-number fallback that the
TZ requires when OperatingBy is null — SU5000-5399 shows Pobeda (DP),
SU5400-5799 shows Aurora (HZ), SU6000-6999 shows Rossiya (FV), and the
3000-4999 / 5800-5999 bands explicitly render no logo.
63 table-driven tests lock in every range boundary and carrier entry.
FlightCard and ScheduleFlightBody both apply the range resolution before
falling back to the flight's own carrier code.
