The InboundAPI carried its own IActiveNodeGate (implemented by Host/Health/ActiveNodeGate)
whose rule already matched the shared Health 0.3.0 AkkaActiveNodeGate — both route to
ClusterActiveNode (oldest Up member). The private interface and implementation are deleted;
InboundAPI references ZB.MOM.WW.Health (0.3.0, already pinned) and InboundApiEndpointFilter,
AuditWriteMiddleware, InboundMethodWarmupService and FlowDebugRunner consume
ZB.MOM.WW.Health.IActiveNodeGate. The Central branch of Program.cs registers
AkkaActiveNodeGate (unscoped, like the active-node health check).
Warm-up behaviour is kept: the shared gate answers false while no ActorSystem resolves, while
this member is not Up, and on any cluster-init fault. It resolves the ActorSystem through the
existing DI singleton bridge (GetOrCreateActorSystem), the same path the health probes use.
Tests: CompositionRoot asserts the shared gate type (fails with the registration removed);
the evaluator wiring test now drives AkkaActiveNodeGate; new warm-up test (no ActorSystem ->
not active). Nothing was missing from the Health 0.3.0 package.
