Class ModalOptionSignalDispatcher

Dispatches a modal option's submit signals, exactly once per press.

The press is not naturally once: a modal option's signals are dispatched synchronously, and one of them can switch the active input action map (EndGameSessionSignal returns to the menu mode, which re-enables the UI map). Re-enabling a map while Submit is still held re-fires Submit on the modal, which is still alive at that moment, so the same option dispatches its whole signal list a second time from inside the first dispatch. The second pass is what destroyed the modal underneath the first one and produced the NullReferenceException on close.

A ReentrancyGate answers this without depending on Input System internals: the nested submit is refused, and the outer one finishes normally. The gate's scope is one dispatcher, which is one modal service, so a submit on a different modal is unaffected.

Accepted limitation: while an option's signals are dispatching, a synchronous submit of ANOTHER option is refused too, not queued. No authored flow does that today — a modal option's signals close the modal or change mode; they do not submit a sibling option — and a queue would need a policy for what to do when the modal is gone by the time the queue drains.
