…king FingerprintStore.Block and Unblock retrieve the user record via GetByFingerprint to find the user's uid, but then sent UserStoreMessages.Update with `uid: fp.uid`, which is the fingerprint id — so the wrong record (or no record) was being updated. Pass the user's uid instead.
The WS authentication middleware previously did
system.send(SessionStore, StoreSession({ uid, actorSystem }));
next(undefined);
— a fire-and-forget that returned the HTTP 101 to the client before the
SessionStore's clientIndex had been updated with the new actorSystem ↔
uid mapping. The browser would then immediately ask actors that resolve
the caller's role via determineRole → SessionStore.GetSessionForClient,
which would miss in clientIndex and return "Unknown client session".
This produced a ~30 second Dashboard reload spinner: the frontend's
afterStart asks (UserAdminActor.GetAll, FingerprintStore.GetMostRecent,
LocalUserActor.GetOwn) would hit timeouts (5s each + 5s sweep) before
the system Promise could resolve and the spinner could clear.
Converting send → ask makes the handshake wait until clientIndex is
populated, so the very first ask the new client sends resolves its
session correctly.
