UnregisterGate is registered via RegisterAction(Unregister) on
construction (Unregister returns void), but Dispose was calling
UnregisterFunc() instead of UnregisterAction(). The mismatched
unregister call leaks the action subscription on plugin reload —
subsequent Dispose/Init cycles would accumulate orphan handlers
in the Dalamud IPC layer.
Pre-existing upstream issue (CodeRabbit critical finding); fixed in
v1.0.0 standalone cut where we own the codebase.
