fix(app): refresh queued inputs when the connection returns - #47573

When the event stream reconnects, the open session reloads its metadata and transcript through createSessionResolution, which re-runs on the connected transition. Queued inputs (session.pending) were only loaded by the timeline's createResource, keyed on the session ID alone, so after a reconnect the composer kept showing the pre-disconnect queue.

• createSessionResolution now starts the pending read alongside the message read, so every connected transition refreshes transcript and queue together.
• sync.run dedupes the concurrent call from the timeline resource, so mounting a session still issues one /inbox request.
