feat: show taxi flight destination indicator below minimap

Stores the destination node name when activateTaxi() is called and
displays a "✈ → <Destination>" indicator in the minimap indicator
stack while isOnTaxiFlight() is true. Falls back to "✈ In Flight"
when the destination name is unavailable.
