Benjamin Carlsson f988ada4bf Reconnect idle Cloud conversations after transient stream loss (#60969) ...

## Why

A lost Cloud reply stream previously required reopening the conversation, even when it was idle. Recover the displayed conversation automatically while holding queued input until its reply stream is usable.

## What changed

- Add bounded retries for transient stream failures in the displayed, idle conversation, with credential and network-policy checks. Keep explicit reopen behavior when recovery is unavailable or fails.
- Enable HTTP/2 keepalive pings for Cloud connections.
- Queue input while disconnected and resume ordinary submission after recovery. Mark recovered history as potentially incomplete so an explicit reopen reloads missed turns while preserving drafts and reconciling pending submissions.
- Store retained input per backend and apply background settings updates to the owning backend's drafts.

## Testing

Add regression coverage for queued input during disconnection and extend resume and backend-handoff tests to cover history refresh, draft preservation, and retained settings.
