Cleanly stop inbound streams during shutdown.

[robholland]

What changed?

When gracefully shutting down, close inbound streams, not just outbound.

Why?

This avoids unexpected connection reset on the sender side.

Flag enabled (default — new behavior):

1. Evict from membership + drain wait
2. handler.Stop() ← stops StreamReceiverMonitor (closes inbound streams + outbound),
   replicationTaskFetcherFactory, shardController, eventNotifier
3. server.GracefulStop() ← stream handler goroutines already unblocked → clean drain
4. visibilityManager.Close()

Flag disabled (current behavior):

1. Evict from membership + drain wait
2. handler.controller.Stop() ← only stops the shard controller (inbound streams left open)
3. server.GracefulStop() ← stream handler goroutines still blocked → falls back to Stop()
4. handler.Stop() ← remainder of handler teardown
5. visibilityManager.Close()

How did you test it?

• built
• run locally and tested manually
• covered by existing tests
• added new unit test(s)
• added new functional test(s)

Note

Medium Risk
Touches history service shutdown sequencing and replication stream lifecycle, which can affect rolling restarts and cross-cluster replication behavior if the new ordering has unintended side effects.

Overview
Improves history service graceful shutdown by optionally closing inbound replication streams (in addition to outbound) so remote senders are signaled to stop and stream handler goroutines can drain cleanly.

Introduces new dynamic config history.enableCloseInboundReplicationStreamOnShutdown (default true), threads it through history Config, and uses it to (a) stop inbound streams in StreamReceiverMonitor.Stop() and (b) reorder service.go shutdown to call handler.Stop() before server.GracefulStop() when enabled; adds unit tests covering both enabled/disabled behaviors.
