In-memory stream stops delivering messages after "Unable to create local activation" and OrleansMessageRejectionException

We are using Orleans in-memory streams, and after some time, the streams stop delivering messages. The logs show repeated activation failures for internal memory stream grains, followed by OrleansMessageRejectionException.

Once this occurs, no further messages are delivered to stream subscribers until the silo is restarted.

```

Start with Orleans.Streaming/MemoryStreams/MemoryAdapterFactory.cs at QueueMessageBatchAsync and Orleans.Persistence.Memory/Storage/MemoryStorage.cs at WriteStateAsync, then reproduce the in-memory stream failure from the reported logs. Trace the activation rejection and verify that stream messages and rendezvous state writes continue after the failure without requiring a silo restart.
