This PR fixes subscribeToLogs and messageStream RPCs; previously, they were staying open when a Session closed. Session closing behavior for a number of RPCs was specifically added as a tests here. I'll note that we are inconsistent in how we handle this case - some RPCs will complete successfully, others will pass along UNAUTHENTICATED or CANCELLED. We should aim to clean this up, but I'm proposing we do that as a follow-up PR to avoid PR bloat.

The fix involves hooking into SessionServiceCallListener, which is a centralized place where we maintain Session state information. We should strongly consider migrating other RPC Session close behavior to here to simplify the implementations and maintain consistency. Again, I'd suggest doing that as a separate PR.

Fixes deephaven#5415
